Convert array of clusters to cluster of arrays without for loop

Hi!
Here's a problem: I've got an array of clusters (array of messages). Each cluster consists of elements of different data types: double (time), cluster (parameters), char (station id), byte (message code). I know one cluster size and the array size. I need to draw a time graph. How can I convert the array of clusters to a cluster of arrays (array of time values, array of parameters clusters, arrays of chars and bytes).
I post this question because in my real array of clusters each cluster consists of 162 elements and some of them are clusters themselves, so I realy dont want to wire "for" loops as was advised in other topics.
Hope to get fresh ideas. Memory management? Type Cast? FlatternStrings and variants? Anything!
Thank you.

Hi, everybody! Glad you read the post!
There is the cluster in the attachment. The application I make is a TCP client. The cluster is a message. Actually I get a string, find edges ("DIAG" - begin, "GAID" - end) and then I use "unflattern to string" for making the cluster. I cann't make another structure of the message - I didn't make the server. My client has a buffer of recieved messages. I need to plot graphs of different cluster elements for all messages in my buffer (for example the Time 1 element). If I use the for loop it would be too slow. The idea was to convert all buffer to a 2D array of U8 and then use type cast to get the cluster of arrays. Then it would be easy to take ane cluster element and send it to graph.
I didn't sucseed yet.

What is your question about?
A) convert the string you get from I don't know where to the giant cluster, the red part in your message, or
B) making a graph out of some element from that giant cluster, who now is in an array, the blue part in your message.
The code you showed us looks a solution for question A but no loop is needed for this. So why bother about a loop that would be too slow here?
Also your code start from an array of U8, so where's the string?
If you could provide a string that needs conversion, we could try another way ... ...
Question B can easily be solved with a for loop and "unbundle by name". Don't know where you get the idea that a loop would be too slow
Open G library has a lot of VI's to retrieve specific elements from clusters, maybe one of those could help solve the problem.

1d cluster array replace value in a 1d boolean array (without using Loop)

Hi ,
is there a way to replace the values (string , boolean) of a 1D array Cluster with value of 1D boolean array without using loop ?

Replace Array Subset requires that the array elements are type compatible with the elements that you want to replace. That seems not the case in your example.
And the For Loop is anything but slow. How many billion elements do you expect your array to have to worry about performance of the for loop? With the type definition of your example even a ready made LabVIEW function would have to do internally a for loop too, since the boolean data inside the original array can not be in a continous memory area.
Maybe if you show us what you try to do with the for loop we can understand better what your concerns are. As it is from the front panel image alone it is really hard to understand what your imagined problem might be.

Is there arrays or FOR loops in ABAP?

Hi everyone!
Is there an array and FOR loops in ABAP similar to the C Language?
If there is, please give example. _
Thanks a lot!

Hi,
There is no array concept in ABAP but there are field-symbols which are same as pointers in C.As for the FOR loop there is no such command in SAP/ABAP but we do have the do..while and loop...endloop commands.There is also CASE statements and if..endif commands.
Thanks,

Finding a minimum value in an array without using loops

I can find a minimum value in an array using a loop, but I am unsure of how to do it without any type of of loop
Here is what I have using a loop:
// This method searches for the minimum value in an array
public static int min(int a[]){
int min = a[0];
for(int i = 1; i < a.length; i++){
if(a[i] < min){
min = a;
return min;
How do I covert this to do the same thing, using no loops?
Thank you for replies

Remove text field from Array via for loop

Hi,
i have a problem to remove text fields added via for loop.
That im doing is, via for loop im dynamically creating menu with 10 buttons.
Each button contain, dynamically created, background (shape) and text field.
And everything is fine.
But when im try to remove text fields then i got this error:
- Im using button to remove text fields - lang_btn.addEventListener(MouseEvent.CLICK, clickHandler);
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.

it looks like those tf's are children of lmButtonsMCArray[i], not the current scope. use:

                                        //clear the array
                                        pushUsTFintoArray = [];
                              else
                                        for (var rNr_eg:Number = 0; rNr_eg < pushEgTFintoArray.length; rNr_eg++)

Build 1D array using for loop

Hi guys,
I am testing out array. How do I create a 1D array of x-y using for loop?

OK, first of all you did not say what the array should contain. If you want an array that has one array element for each iteration of the while loop, you need to first think a bit harder. Your outer loop has no wait, thus it will spin millions of times per second and you will run out of memory soon, no matter how much memory you have. How many times should the while loop iterate? If you know the number before the program starts, you would use a FOR loop and autoindex at the loop boundary.
If you want to use a whiile loop, you need a mechanism to keep the array size reasonable. For small final arrays, you can just build the array in a shift register if you need it updated as it happens. If you only need the array after the loop stops, you can autoindex at the right loop boundary.
In any case, you should take a step back and decide what you really want. Currently the specifications are very vague and unreasonable.

How do i use Arrays and For Loops in Loading Multiple Images?

I am struggling to load a sequential array of images to appear like a moving image. So when u click the button the images load one after the other.
The code below is what i have so far, but it fails to do what i seek in that there's only one image loading which is the last image in the array, so either because the images are stacking up atop each other, or because i simply dont understand the basics...
And, i am unclear about what you said kglad, that my solution will be more complicated because i need to preload my image sequence and then use a loop to load it?
import flash.net.URLRequest;
import flash.display.Loader;
var count:int = 0;
var imageArray:Array=["1.jpg","2.jpg","3.jpg","4.jpg","5.jpg","6.jpg","7.jpg",
"8.jpg","9.jpg","10.jpg","11.jpg","12.jpg","13.jpg"];
for(var i:uint=0;i<imageArray.length;i++){
var btn:YourButton=new YourButton();
btn.ivar=i;
addChild(btn);
btn.x=0;
btn.y=0;
btn.addEventListener(MouseEvent.CLICK,clickF);
var ldr:Loader=new Loader();
addChild(ldr);
ldr.x=20;
ldr.y=20;
function clickF(e:MouseEvent){
    ldr.load(new URLRequest("D:/flash cs5.5/image_sequence/twirlSeq/"+imageArray[e.currentTarget.ivar]));
function loadComplete(e:Event){
     // first process loaded image, then...
    count++;
    if(count < imageArray.length){
        loadCurrentImage(); // load the next image
    } else {
        // sequencial loading complete, carry on to next activity
function loadCurrentImage(){
     ldr.load(imageArray[count]);
     ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete);

create a new fla, add btn and add the code i suggested. test.
var count:int;
var imageArray:Array=["1.jpg","2.jpg","3.jpg","4.jpg","5.jpg","6.jpg","7. jpg",
"8.jpg","9.jpg","10.jpg","11.jpg","12.jpg","13.jpg"];
var ldr0:Loader=new Loader();
ldr0.contentLoaderInfo.addEventListener(Event.COMPLETE,loadCompleteF);
var ldr1:Loader=new Loader();
ldr1.contentLoaderInfo.addEventListener(Event.COMPLETE,loadCompleteF);
btn.addEventListener(MouseEvent.CLICK,clickF);
function clickF(e:MouseEvent):void{
// initialize count
count=0;
// call loadF
loadF();
function loadF():void{
// add one of the loaders to the top of the displaylist and load the next image
addChild(this["ldr"+count%2])
this["ldr"+count%2].load(new URLRequest(imageArray[count]));
function loadCompleteF(e:Event):void{
// increment count
count++;
// check if the last has loaded
if(count<imageArray.length){
// if not clear the content out of the next loader.
if(this["ldr"+count%2].content){
this["ldr"+count%2].unloadAndStop();
// and call loadF so the next loader can load the next image in the array
loadF();
} else {
// if the last has loaded.
// last load completed

Añadir fila a array autoindexing for loop

Hola a todos,
Quería saber como puedo hacer para añadir una fila automaticamente a un array cada vez que se produce un cambio en mi array "Introducir datos". Creo que la solución es el tema de crear un bucle for y el autoindexing. Para que me entendais mejor he puesto en el vi adjunto un bloque que hace lo mismo que pretendo conseguir, pero teniendo que pulsar un botón.
Muchas gracias

Hola Davidll,
Te adjunto un VI que añade una fila a una array cuando se cumple una condición. En este caso la condición es presionar un boton booleano.
Fijate que hemos usado una variable local para escribir sobre la matriz que ya existe y simplemente con la función "Build array" añadimos una fila nueva con los valores de nuestro control "Fila a insertar" que noes más que una array de una dimension.
Si tienes algún otro problema con arrays recuerda que dispones de una gran cantidad de ejemplos básicos en la pestaña Help/Find examples..
Son bastante útlies y explicativos.
PD:El boton esta configurado como "Latch when pressed" en la "Mechanical Action" para que solo produzca un pulo a nivel alto y velva a estado bajo. Sino produciria pulsos constantemente y se añadirian infinitas filas a nuestra array.
Que pases buen día!

Indexing array without a loop

I would like to make and insert elements to each index on an 1D array. but, I don't want to use loop. How can I input my data into 1D array increasing and indexing array? whenever We want to make a new array, Do We have to use a loop control?

To create an array, all you have to use is the Initialize Array function or just drop an array constant onto the diagram. You can then use either Replace Array Subset or Insert Into Array.

Using while loops instead of for loops in arrays?

I am new to java and doing a java tutorial on using arrays and for loops. What im trying to find out is how it is possible to use a while loop instead.
I would be very grateful if anyone can suggest a way of changing my code to use a while loop.
The code I have written is:
public class DetermineGrade
public static void main(String[]args)
final char[] mark = {'A','B' ,'C' ,'D' ,'F' };
char [] grade = new char[5];
int [] Score ={95,35,65,75};
for (int i=0; i<4; i++)
if (Score >= 90)
grade= mark[0] ;
else if (Score >=80)
grade = mark[1] ;
else if (Score >=70)
grade = mark[2] ;
else if (Score >=60)
grade = mark[3];
else grade = mark[4];
for (int i=0; i<4; i++)
System.out.println("grade = " + Score + ", " + grade);
Thankyou LB

Im trying to underdstand the differences in the
different loops. I can grasp the for loop but I dont
see how a while loop works, or how it id different
from the other?
for (j = INIT; j < MAX; j++) {
    // do stuff
}is the same as
j = INIT;
while (j < MAX) {
    // do stuff

Help on changing array elements with For loop

Hi,
I'm wondering if anyone can help me with this problem. I'd like to be able to modify elements of an array with For loop. In the attached VI, my goal is to have an array of [0 1 2 3 4 5], but instead what I've got is [2 2 2 2 4 5]. I initialized the array with a value of 2 to help me identify which elements are changing. Can anyone help me pointing where my mistake is? Thanks.

It's a classic issue for LV newbies. In this case you HAVE to use a
shift register otherwise the modifications of previous cicles are lost.
It's all easier than it's seems, see attached vi.

Easier way to convert array to cluster with named variables?

I have an array of variables, I would like to essentially unbundle that array to named variables.
I believe the only way of doing this is by converting the array to cluster (besides removing each element one by one)?
Is what I have done below the best way of doing it? seems a bit weird having to unbundle and rebundle by name.
comments appreciated.

Your problem code is actually right before the red square. Instead of the "array-to-cluster-unbudle dance", you should simply use a plain index array resized for the same number of outputs. same functionality, less convoluted.
Your wiring is a bit of a mess and it is hard to tell if the order of elements in the array is the same as in the cluster. Maybe a simple typecast to the cluster would work.

Converting Array Objects into ArrayCollections

Hi,
I am facing problem with converting Array Objects into ArrayCollections. How can i convert Array Objects into ArrayCollections. If any one knows how can we do that Pl reply.
Thanks in advance to all

Hi Bhasker,
thanks for u r reply. Here i attached screen shot of my server "data.result".
My proxy varaible contains
My object varaible "obj" contains
After parsing the result my arraycollection contains, (i mean after converting Object to Array to ArrayCollection) the below information. For information Pl find the attached arraycollection.png image. In the attached image my arraycollection name is "users".
Here i pasted the code that i used to convert "ObjectProxy" to "ArrayCollection"
var proxy:ObjectProxy = ObjectProxy(data.result);
            var obj:Object = proxy.object_proxy::object;
            var arrycoll:Array = ArrayUtil.toArray(obj);
            model.users = new ArrayCollection(arrycoll);

Converting a single entry within an array into 16 entries within a new array. Building an array without knowing the exact amount of array entries.

I'm developing a VI that reads a text file and does a manipulation on the data it reads. The VI does the following: First, it reads all the ASCII characters from a text file, converts them to 8-bit words, until EOF occurs. Then I do some simple conversion to each byte. The result is that each bit entry of the byte now gives 2 3-bit entries, making a total of 16 3-bit values returned for each byte within the original array. For example, when I read element #0 of the byte array, I get the byte value of 1011000. My VI then converts this to 16 seperate 3-bit values. I can do the conversion just fine. My pro
blem is figuring out how to put these 16 elements into an array to be written out of my 6534 card. I know how to do the DIO write part, but the problem is how do I combine the 16 elements into an array for thousands of bytes read from the text file? Also, the size of the file that I read is unknown until it is read, so I may have to output many sucessive outputs as described above. The first element read would give 16 3-bit elements for the new array, the second byte read would give another 16 3-bit elements and so on upto N values in the original array. Any ideas ?

Place a for loop, wire N with your readed string lenght, pass the string inside and wire it to string subset, with the lenght entry wired to 1 and the offset entry to the loop counter (i). Then, you can play with every character inside the loop, and have an output array composed with the result of every character.
Hope this helps

Having trouble converting array to spreadsheet string, storing the file and coverting back to array with complex numbers

I am working with a network analyzer. I have arrays made of 5 columns the first consisting of an integer and the next four consisting of complex numbers. I am converting the array into a spreadsheet string and then saving the file using the write characters to a file VI. That seems to work well as when I open the file in Excel all the data is there. However when I try to reverse the process, open file and convert back to array, I loose some of the data. Specifically the imaginary parts of my complex numbers are all going to zero. I have narrowed down the problem to be in the conversion from spreadsheet string to array and vice versa. I
think the problem may be with the 'format' input to the VI. I do not have an adequate resource for this so I am not sure what to put in to accomplish my task. Any takers?

Hi Biz
I don't think there is a direct way of converting a complex number to a
string, so when you convert the array to a spreadsheet string, the
numbers would be converted to real data.
However, you could try separating the real and imaginary parts using the
"Numeric: Complex to Re/Im" function, and then store these - either in
separate files or in adjacent columns/rows in the same file. Then, when
you read in the data again, use the "Numeric: Re/Im to Complex" function
to put the two "halves" together.
If you actually want Excel to interpret the numbers as imaginary, then
you'll probably want to create a string for each complex number of the
form "Re + Im*i" (after separating the Re and Im parts), by using
"String:Format into String" with 2 numeric inputs and the format string
"%f+%fi".
Reading the data back into Labview then would require splitting the
string into the 2 pieces by using "Stringcan from String" with 2
numeric outputs (smae precision as original numbers specified by the 2
Default Value inputs) and the same format string "%f+%fi", and then using
the above-mentioned "Numeric: Re/Im to Complex" function. It worked for
me, so if you can't follow what I am describing, send me an email and I
can email you what I did (LV 5.1.1).
