1D Boolean Array to 1D Integer Array conversion for FPGA FIFO

Hello, I am using a PXI7813R card. I would like to pass some data between the target (FPGA) vi and the host vi using the FIFO. I have a FIFO setup to 1023 "32 bit integer" samples. I have a boolean array of 32000 samples which would be the same as 1000 32 bit integers, that I acquired using the PXI7813R card. I would like to convert the 1D boolean array to a 1D "32 bit intger" array. This seems like a more a difficult problem than I first thought as the labview functions are reduced when targetting a FPGA device. I have attached a jpg of how I would like to do it. I am getting a "Arrays must be fixed size in current target" error for the output from the array subset function. I know this is because one of the inputs is not exactly a constant, i.e. the index input for array subset, but regardless of the index, I will only ever be taking 32 bits from the boolean array at any time to convert to a 32 bit integer to then place in the FIFO. Any suggestions of how I may get around this problem would be gratefully recieved. Regards, Michael.

Hi Daniel,
Thanks for your reply.
I had a look at the thread that you suggested and I'm not sure if that would solve the problem I was having, the option box was checked as default. I think my issue has to do with the limitations of the different LV functions when targeting a FPGA device.
I have decided to take another route anyway, it seems that trying to compile a large array (even a 1D boolean array) for a FPGA target both takes a long time and also a lot of FPGA resources.
Thanks again for your reply,
Regards,
Michael.

Guys!! any one can help me in recursive permutation of integer array!!

this is the description of my problem:
We are supposed to develop a recursive method with the following header:
public static boolean nextPermutation(int[] array)
The method receives an integer array parameter which is a permutation of integers 1, 2, �, n. If there is �next� permutation to the permutation represented by the array, then the method returns true and the array is changed so that it represents the �next� permutation. If there is no �next� permutation, the method returns false and does not change the array.
Here is a verbal description of the recursive algorithm you need to implement:
1. The first permutation is the permutation represented by the
sequence (1, 2, �, n).
2. The last permutation is the permutation represented by the
sequence (n, �, 2, 1).
3. If is an arbitrary permutation, then the �next� permutation is
produced by the following procedure:
(i) If the maximal element of the array (which is n) is not in the first
position of the array, say , where , then just swap and . This
will give you the �next� permutation in this case.
(ii) If the maximal element of the array is in the first position, so ,
then to find the �next� permutation to the permutation , first find
the �next� permutation to , and then add to the end of thus
obtained array of (n-1) elements.
(iii) Consecutively applying this algorithm to permutations starting
from (1, 2, �, n), you will eventually list all possible
permutations. The last one will be (n, �, 2, 1).
For example, below is the sequence of permutations for n = 3 , listed by the described algorithm:
(0 1 2) ; (0 2 1) ; (2 0 1) ; (1 0 2) ; (1 2 0) ; (2 1 0)
if any one can help me then please help me!! i am stucked at this position to find permutation of the integer array.
thanks,

Sure. Why don't you post the code you already have done, and maybe
someone here can help you with it.

2 parts: 1) integer array to string 2) string out to a jTextField

I am completely new to Java and Netbeans, but I'm writing my 1st
application that takes a "hex" character input from a jTextField,
then converts it to an "binary" integer array. I then do a lot of bit
manipulation, and generate a new "binary" integer array.
String myhex = jTextField1.getText();
    int len = myhex.length();
    int[] binarray = new int[len*4];
        for (int i = 0; i < len; i++) {
           if (myhex.charAt(i) == '0'){
              binarray[4*i]=0;
              binarray[4*i+1]=0;
              binarray[4*i+2]=0;
              binarray[4*i+3]=0;
           else if (myhex.charAt(i) ==
           // repeat for '1 to 9' and 'a-f/A-F'
           // generate new integer array(s) using various bits from binarrayI realize it might not be the best way to do the
conversion, but my input can be of arbitrary length,
and it is my first time trying to write Java code.
All of the above I've completed and it works...(thanks Netbeans
for making the gui interface design a real breeze!)
So I end up with:
binarray[0]=0 or 1
binarray[1]=0 or 1
binarray[2]=0 or 1
binarray[n]=0 or 1
Where n can be any number from 0 to 63...
I then manipulate the bits in binarray creating a new integer array
and for the sake of expediency let's call it "newbinarray".
newbinarray[0]=0 or 1
newbinarray[1]=0 or 1
newbinarray[2]=0 or 1
newbinarray[n]=0 or 1
Where n can be any number from 0 to 63...
I first need to know how to convert this "newbinarray" integer array to a string.
In the simplest terms if the first three elements of the array are [0][1][1],
I want the string to be 011.
Then I want to take this newly formed string and output it to a jTextField.
string 011 output in JTextField as 011
I've scoured the net, and I've seen a lot of complex answers involving
formatting, but I'm looking for just a simple answer here so I can finish
this application as quickly as possible.
Thanks,
Thorne Kontos

Code for how to read an integer array from the command prompt...

hello,
Could anyone give me the code for how to read an integer array from the command prompt...its very urgent!..

If you are using a recent version of Java (5 or later) you can use Scanner:
http://java.sun.com/javase/6/docs/api/java/util/Scanner.html
That page has some example code on it, too.

Writing an integer array to a file...

Okay, so I just wanna write a sorted integer array to file... but I'm having a problem or two.
int[] array = read(new File("C:\\college work\radixsort.txt");
radixSort(array, array.length);That text file is a list of 30 numbers.
After the radixSort method is called the values in the text file are sorted into the correct order. Then I want to write the sorted values to a text file radixSorted.txt
I had too many problems with printArray() so I figured this could be easier.
I have tried FileInputStream and FileWriter but no luck.
I don't want the answer, but just something to help point me in the right direction.
Thank you.

pri.println(char[] x) looks like the one I am looking for.
I have modified the code. I've placed only the println part inside the loop now, but it's just the pri.println(char[], array) now. I'm nearrrrly there! (I think).
try
               PrintWriter pri = new PrintWriter(new FileWriter("C:/college work/radixsort.txt", true));
               for (int h = 0; h < array.length; h++)
                    pri.println(char[], array);
          catch (Exception e)
               e.printStackTrace();
               System.out.println("No such file exists.");
          finally
               pri.close();

Saving an integer array into a .txt file

hii, im only a beginner in java, so this is the only code i've learned so far for saving array elements into a file
     public static void saveNames(String [] name) throws IOException
               FileWriter file = new FileWriter("Example\\names.txt");
               BufferedWriter out = new BufferedWriter(file);
               int i = 0;
               while (i < name.length)
                         if (name[i] != null)
                              out.write(name);
                              out.newLine();
                              i++;
               out.flush();
               out.close();
However, this is only used for string arrays; and i can't call the same method for an integer array (because it's not compatible with null)
I don't really understand this code either... since my teacher actually just gave us the code to use, and didn't really explain how it works
I have the same problem for my reading a file code as well --> it's only compatible with string
     public static String [] readNames (String [] name) throws IOException
          int x = 0;
          int counter = 0;
          String temp = "asdf";
          name = new String [100];
          FileReader file = new FileReader("Example\\names.txt");
          BufferedReader in = new BufferedReader(file);
          int i = 0;
          while (i < array.length && temp != null)                    // while the end of file is not reached
               temp = in.readLine();
               if (temp != null)
                    name[i] = temp;                    // saves temp into the array
               else
                    name[i] = "";
               i++;
          in.close();                                   // close the file
          return name;
Could someone suggest a way to save elements from an integer array to a file, and read integer elements of that file?
Or if it's possible, replace null with a similar variable (function?), that is suitable for the integer array (i can't use temp != 0 because some of my elements might be 0)
Thanks so much!!!!!

because it's not compatible with nullI think it should be okay to just remove the null condition check since there are no null elements in a primitive array when writing.
Use Integer.parseInt() [http://java.sun.com/javase/6/docs/api/java/lang/Integer.html] to convert the String into an Integer when you read it back and use Integer.toString() to be able to write it as a String.

How to bind SelectManyChoice to Integer array parameter

Hi.
I am using JDev TP4. I need to populate an integer array with the keys of the items selected in a SelectManyChoice.
I have created a page with a parameter form for the three parameters and a readonly table for the result class from a data control for this method:
public FreeGuaranteeModel[] getFreeGuarantees(Timestamp firstDate, Timestamp lastDate, Integer[] companyIds)
In the parameter form i have created a SelectManyChoice which displays a list
from a viewObject by dragging the companyIds parameter onto the parameter form, creating a SelectSingle component and then converted it to a SelectManyChoice.
The page renders ok, I can select one or more items in the list, but when I press the button to execute the method, the companyIds array is empty.
(The two date parameters are populated).
What am I missing? Is the binding wrong? I am new to JDev so if there is some other way to do this, please let me know.
This is the relevant part of the jspx:
<af:selectManyChoice value="#{bindings.companyIds.inputValue}"
          label="#{bindings.companyIds.label}"
          shortDesc="#{bindings.companyIds.hints.tooltip}"
          binding="#{backing_ViewFinancialResult.selectOneListbox1}"
          id="selectOneListbox1">
<f:selectItems value="#{bindings.companyIds.items}"
     binding="#{backing_ViewFinancialResult.selectItems1}"

Hi,
Thank you for your answer.
Following the example I was able to get the selected entries into an Integer array property with accessors which I created in a managed bean.
But I have not been able to get the values into the companyIds parameter of the method to execute.
Is there a way to bind directly to this parameter, or do I have to collect all parameters through separate properties and then call my method manually when the button is pressed?

Passing a integer array client to server

Hi
Is it possible to pass integer array from client to server
Through soap.
Basically i want to pass this array buffer
int[] buffer = new int[(int)len];
     for(int i=0;i<len;i++){
          buffer[i] = F.read();
          System.out.print(buffer[i]+ " ");
Nams Thanks

Yes, if the server is written to accept one.
To create a server to accept one, create a service endpoint
interface that has a method that takes a int[] as a parameter and
generate the service from that by following the steps in the jaxrpc
tutorial. Then generate the client from the generated WSDL.

Converting a string to an integer array

This is kind of a newbie question, but:
If I have a string which looks like this: "12,54,253,64"
what is the most effective/elegant/best/etc. way to convert it into an integer array (of course not including the ","s :-)
Any suggestions are greatly appreciated.

Thanks, I'll do that. I was looking at StringTokenizer and other things, but it seems they are not implemented in j2me?

How to return array of unsigned integer pointer from call library function node & store the data in array in labview

Did you take a look at the example that ships with LabVIEW that shows how to do all sorts of data passing to DLLs. I believe your situation is one of the examples listed. You can find the example VI in the "<LabVIEW install directory>\examples\dll\data passing" directory.

Suggestion: Macros or a way to unroll loops? Integer array input? Shader Model 3 and 4?

I think it would be nice if pixel bender supported a way to unroll loops. In it's current state certain shaders are really awkward to write or just get ugly when they're converted for flash player. I know it wouldn't be that hard for the developers to just unroll constant sized loops. Things such as:
for (int i = 0; i < 10; ++i)
if (foo) { ... }
can be unrolled easily. Either that or add in some code generation feature that allows this with a preprocessor system. Or better yet add in support for loops since it only requires shader model 3 or equivelant from GLSL.
This brings me onto another point. Is there going to be support for Shader Model 4? I'm talking about bitwise operations and integer types. Even if you don't allow native support for byte array adding texture sampling for bytes, shorts, and integers would be nice. Also allowing this to work in flash would be nice with the ability to tell the user they don't have shader model 4 or be able to detect compatability and use a different shader.
Integer arrays would be nice to allow to as input then to the shader. I noticed the reference manual already mentioned:
"NOTE: Pixel Bender 1.0 supports only arrays of floats, and the array size is a compile-time constant. Future versions of Pixel Bender will allow arrays to be declared with a size based on kernel parameters, which will enable parameter-dependent look-up table sizes."
Again support for these features in flash player would be really nice.
Targetting the lowest GPUs is really limiting the true power of pixel bender. I wrote this for fun: http://assaultwars.com/pictures/raycasting6.png which is just a simple real-time voxel raycaster. However, it could be so much more powerful if pixel bender supported more of the GPUs features. Even simple things like custom functions would be really handy in flash player. I'm thinking of this more oriented toward flash games too where more powerful features are unlocked based on the user's GPU.
If this is already planned for a future pixel bender release then nevermind. I didn't see a developers blog or any news about future versions.
Interesting:
http://forums.adobe.com/thread/36659?tstart=60
Apparently Kevin said "Look for them in a future version of the language as cards that support these features become common." in regards to bitwise operators aka Shader Model 4.

Here's an example, not using NetBeans:

        for (int value : newbinarray)
            sb.append(value);
        String st = new String(sb);
        this.add(new JTextField(st));
    private static void createAndShowGUI()

Sorting a two-dimensional integer array

I have a 2-D array that looks simliar to this:
1 0 0 0
1 1 0 0
2 0 0 0
2 1 1 1
1 2 1 0
2 1 2 0
3 1 1 1
4 1 0 0
2 1 1 2
.I am trying to come up with an algorithm that will sort this array by the first column, then the second, then the third, then the fourth. But I'm stumped. The array above should look like this when sorted:
1 0 0 0
1 1 0 0
1 2 1 0
2 0 0 0
2 1 1 1
2 1 1 2
2 1 2 0
3 1 1 1
4 1 0 0I've been able to sort 2-D arrays with only two columns, but this has been a new challenge for me. I've been able to come up with a brute force approach but it doesn't seem to work, nor is it very efficient. Any suggestions on how to approach this problem would be a great help.

An 2-D array is simply an array of arrays, so you should be able to use a simple Comparator:
class ArrayIntComparator implements Comparator
    public int compare(Object o1, Object o2)
         int[] arr1 = (int[]) o1;
         int[] arr2 = (int[]) o2;
         for (int i=0; i<=arr1.length; ++i)
            if (arr1[i] != arr2)
return(arr2[i] - arr1[i]);
return 0;
int[][] arr2d = ...
Arrays.sort(arr2d, new ArrayIntComparator());
Didn't compile it, but it oughta give you a close start.

Bytes array to double words array

I have an array of bytes. I need to take 4 bytes at a time to create a doubleword (32bits).
I am currently using Decimate Array and Join Numbers twice to do this.
Is there a more efficient way of doing this that I am overlooking?
Solved!

Can you explain in more detail what I would do in this case?
As I noted, you can use the Unflatten From String. Since the data is coming from a TCP Read you can wire that directly to it:

Memory/Speed of Split 1D array vs Delete from array

Just wondering how Split 1D array works - does it create two new arrays in a new section of memory or does it just split the existing array in two, reusing the memory in place. (assuming that the original array is not needed elsewhere). If the latter is the case then presumably it is more efficient to use split array than delete from array if I want to remove element(s) from the beginning or end of the array. Is there a speed advantage as well?
If I use split array but don't then use one of the output arrays is that memory deallocated or does the array remain in memory?
Thanks
Dave

Ok please ignore the results I posted earlier, they are rubbish - not least because I got the column headings mixed up but also because my code was full of bugs
So, here is a revised table, and the code - which hopefully only contains a few bugs... I'm not clued into benchmarking yet so please feel free to rip the code apart.
I still get different results depending on where in the array I split it, most noticeably with subset and reshape. There is no effect with split. I'm guessing this is to do with the memory allocation. (I have not preallocated memory in my code, but I did wire the output arrays to Index Array)

C# compiling error: 'System.Array' does not contain a definition for 'Select' and no extension method 'Select' accepting a first argument of type 'System.Array' could be found (are you missing a using directive or an assembly reference?)

Hello experts,
I'm totally new to C#. I'm trying to modify existing code to automatically rename a file if exists. I found a solution online as follows:
string[] allFiles = Directory.GetFiles(folderPath).Select(filename => Path.GetFileNameWithoutExtension(filename)).ToArray();
string tempFileName = fileName;
int count = 1;
while (allFiles.Contains(tempFileName ))
tempFileName = String.Format("{0} ({1})", fileName, count++);
output = Path.Combine(folderPath, tempFileName );
string fullPath=output + ".xml";
However, it gives the following compilation errors
for the Select and Contain methods respectively.:
'System.Array' does not contain a definition for 'Select' and no extension method 'Select' accepting a first argument of type 'System.Array' could be found
(are you missing a using directive or an assembly reference?)
'System.Array' does not contain a definition for 'Contains' and no extension method 'Contains' accepting a first argument of type 'System.Array' could be
found (are you missing a using directive or an assembly reference?)
I googled on these errors, and people suggested to add using System.Linq;
I did, but the errors persist.
Any help and information is greatly appreciated.
P. S. Here are the using clauses I have:
using System;
using System.Data;
using System.Windows.Forms;
using System.IO;
using System.Collections.Generic;
using System.Text;
using System.Linq;

Besides your issue with System.Core, you also have a problem with the logic of our code, particularly your variables. It is confusing what your variables represent. You have an infinite loop, so the last section of code is never reached. Take a look
using System;
using System.Collections.Generic;
