Sort array in TestStand
Hi,
I have an array of custom type container, something like:
- TestName
- Type
- Operation
I'd like to sort this array by Type and Operation.
Is that possible in TS 2010? If not - what is the best way to do that? I'm using also LabVIEW and C/C++.
Thanks in advance
Solved!
Go to Solution.
In this case I would recommend passing it to LabVIEW and let LV handle the heavy lifting: http://forums.ni.com/t5/LabVIEW/Sort-1D-array-of-clusters-by-the-second-element-in-the-cluster/td-p/...
Check out Darren's post. It's a clean sort of clusters.
TestStand isn't designed for complex algorithms. Although you could probably do it in TS you would have to come up with the algorithm.
Cheers,

How to call a CString array from TestStand
I have a C++ DLL that uses a CString array, CString myString[ ], that I need to pass back to TestStand 4.0 for inclusion in my results database.
In the TestStand module definition the parameter argument Description comes up as a CStriing pointer (CString*) instead of a CStringArray.
When I put my array of strings into the Value Expression I get an error: Expected String, found Array of Strings.
I have no trouble passing just a string pointer but that's not working either.
Can someone help?
Thanks,
Steve SHi Steve,
I don't think that you can pass a CString Array from C++ DLL to TestStand 4.0 directly.
But you can do it another way: concatenate all Strings by a delimit in your CString Array to build a new String, then pass it to TestStand. In TestStand you can separate those Strings by the delimit, and rebuild a String Array.
For example:
// If this is your CString Array.
CString myString[] = {"AAA", "BBB", "CCC"};
// Build a new String in your C++, and pass it to TestStand.
char *myNewString = "AAA~BBB~CCC";
// Separate myNewString and build an Array in TestStand...
Hope that can help you!

TreeSet vs Collection.Sort / Array.sort for Strings
Gurus
I am pondering weather to use TreeSet vs the Collections.sort / Array.sort for sorting Strings.
Basically I have a list of Strings, i need to perform the following operations on these Strings
1) Able to list Strings starting with a Prefix
2) Able to list Strings Lexically greater than a String
Any help would be greatly appreciated!

Thanks a bunchBig-O wise, there's no difference between sorting a list of N elements or inserting them one by one in a tree-set. Both take O(n*log(n)). But both collections are not well suited for looking up string that start with a certain substring. In that case you had better use a Patricia tree (or Radix tree).
Good luck. -
Sun C++ std::sort coredump during sorting array of long values
Hello,
I got core dump during execution following test program on both Solaris 9 (compile by CC: Sun C++ 5.5 Patch 113817-19 2006/10/13) and Solaris 10 platforms (compile by CC: Sun C++ 5.9 SunOS_sparc Patch 124863-01 2007/07/25).
Core is dumped during sorting array of about 120k elements of unsigned long types using STL std:sort. The input data is available at link: [file.txt|http://www.savefile.com/files/1924004]
When I change sorting methods to std::stable_sort program works fine.
The funny thing is that when I change order of last two values of input data (swap), sorting is successful with std::sort.
Can anyone tell me if it is Sun C++ compiler bug ?Can I use std::stable_sort method safely?
Below code:
#include <iostream.h>
#include <fstream.h>
#include <set>
#include <string>
int main( int argc, char** argv )
char readStr[256];
ifstream file;
unsigned long *l;
int i=0;
l = new unsigned long[119016];
if (l ==0)
cout << "Error in allocate memory";
return -1;
file.open("file.txt");
if (!file)
cout << "Error in openening file";
return -1;
while(file.getline(readStr, 256,'\n'))
cout << readStr<<endl;
l= atol(readStr);
cout << l[i]<<endl;
i++;
std::sort(l,l+119016); //core dump here!!!
for (i=0;i<119016;i++)
cout <<l[i]<<endl;
file.close();
delete [] l;
return( 0 );
Greetings
RobertYou have run into bug 6588033 "std::sort from libCstd loops", which is fixed in current patches.
Get the current patches for Sun Studio and also the current patch for the C++ runtime libraries (SUNWlibC patch).
You can find them here:
[http://developers.sun.com/sunstudio/downloads/patches/index.jsp]
Sun C++ 5.5 probably does not have the fix, since it is quite old and falling out of support.
C++ 5.9 does have the fix. -
I need sorting VI that returns the sorted array element's positions in the unsorted array
I need a VI that will very quickly (n log n) sort a 1D array of doubles. This VI should not only output the sorted array, but for each of the sorted array elements, it should also output that sorted array element's position in the unsorted array. So for example if the input array were:
unsorted_array
4.1
2.3
7.0
5.6
10.2
Then the output arrays would be:
sorted_array
2.3
4.1
5.6
7.0
10.2
indices_array
1 (the value 2.3 is located at position 1 in the unsorted_array)
0 (the value 4.1 is located at position 0 in the unsorted_array)
3 (the value 5.6 is located at position 3 in the unsorted_array)
2 (the value 7.0 is located at position 2 in the unsorted_array)
4 (the value 10.2 is located at position 4 in the unsorted_array)
This way I could generate the sorted_array using just the indices_array and the unsorted_array. Has anyone written a nifty piece of code to do this? I did some research on (n log n) sorting algorithms but most of them use recursion which I don't know how to do in LabVIEW. It would also be nice to have an algorithm like this that could sort an array of strings.
cheers,
RichardTry something like the attached example (LabVIEW 7.0). I think it does what you need.
(To understand the code, it is important to know that arrays of clusters are sorted by the first element in the cluster).
Sort array itself sorts also array of strings, so you could just substitute, keeping the rest of the code the same.
Sort array uses a variation of quicksort, so it should have about NlogN complexity.
(If you think you only need the array of indices to later generate the sorted array, it does not make much sense to even do it. To get the indices, you need to sort the array anyway. You should just sort the plain array directly.

testingfileIO.vi 35 KBHi.
It's nice to have "sorting array" icon.
But I have problem with programming similar option. I want to sort my sine samples taken in more periods to just one period.
Beside defining that mycurrent sample should be less than next one, and greater from previous one in one case, I should take in consider that derivation could be positive or negative. While negative derivation, next sample should be less then current and so one.
Can someone help me with programming?
I've extracted the first period, and then I have to go trough each sample and compare him. When logic is well,I get the index and putinsert elemt in array.
I think that I'm having problem with while loops. I don't know where to put them.
I'm attaching VI. beacuse I'm working on Labview 9.0, I'm attaching also a pic.
Thanks in advance.

Sorting array vs sorting paginated array
...pulling in a long list of photos in a gallery, and I have
a sort function working within the pages of data fine. I need to
bring it back out of the paging stuff so that it sorts the data,
THEN passes to the paging function.
My data comes from mysql > php > xml > Flex into an
ArrayCollection, referred to in MXML as {acSlides}.
Pass the array collection to the paging system like:
<utils:FXCPager id="fxcPager" pageIndex="{currentPage}"
pageSize="{pageSize}" dataProvider="{acSlides}" />
then assign in repeater:
<mx:Repeater id="slideRepeater"
dataProvider="{fxcPager.pageData}">...</>
There is a button for sorting that calls a function a la:
private function sortByRating():void {
var sort:Sort = new Sort();
sort.fields = [new SortField("rating",false,true)];
fxcPager.pageData.sort = sort;
toggleRating = false;
fxcPager.pageData.refresh();
What do I need to do to get this sort function to work on the
{acSlides} array collection instead of {fxcPager.pageData} ???
Thanks!OK I have resolved the error by importing the class adGroup. However now I am back to the original problem which is how to sort the DisplayName alphabetically and keep the associated link in tact. I created the class to avoid sorting parellel arrays but I am afraid it solved nothing as I have no idea how to sort the class. I tried just sorting it like an array:
Arrays.sort(bAD.getGroups()but receive the following error:
java.lang.ClassCastException: com.mylbean.adGroup incompatible with java.lang.Comparable
at java.util.Arrays.mergeSort(Arrays.java:1160)
at java.util.Arrays.sort(Arrays.java:1131)
>
I would assume this message is caused because I cannot sort a class array using this method. But being newer to Java I really have no idea how to get the class to sort by DisplayName before displaying to the user.
So at this point the code works fine but how do I display alphabetically? All suggestions are appreciated. -
I am trying to sort an array of telephone directory information by last, first names, but am having trouble understanding how to use the compareTo method to do so. I thought I could use Arrays.sort, but this doesn't seem to work....any help would be appreciated.
public static Person [] sort(Person [] people) {
Person [] sorted = Arrays.sort(people);
return (Person[])sorted.toArray(new Person[sorted.size()]);
}/* end sort method */
//From Person class
public int compareTo(Object o) {
Person p = (Person)o;
int temp;
if((temp=getLastName().compareTo(p.getLastName())) == 0)
if((temp=getFirstName().compareTo(p.getFirstName())) == 0)
//not sure what to do here
return temp;
}You want to return a negative or positive or zero integer if this item is less than, greater than, or the same as, the object passed as an argument, right? (Read the API.)
You're trying to sort by last name first, and if they're the same, then the first name, right?
So you're not really checking for zero, you're checking for non-zero.
I'm assuming that first name and last name are given by strings, which implements Comparable. So you can do:
public int compareTo(Object o) {
Person p = (Person)o;
int temp = getLastName().compareTo(p.getLastName());
if (temp != 0)
return temp;
// implicit else here
// MORE CODE GOES HERE
}I'll let you do the "MORE CODE GOES HERE" as an exercise.
BTW if you're implementing Comparable, you should probably be overriding equals() as well. -
I have a unsorted array as follows:
array_index = {0 1 2 3 4 5 6 7 8}
array = {1 2 4 3 4 3 4 2 1}
I would like to get the previous index of sorted array as follows:
old_index = {2 4 6 3 5 1 7 0 8}
arrray.sort doesn't return the index the previous index, please help me.You can do that using by creating an array containing the numbers 0 to n in increasing order and sorting that using a comparator that actually compares the content of the original array at the indices provided to it instead of the values themselves.
But why would you need that? Could you describe your requirement in a broader scope? -

Math operations on array in TestStand
Hi.
I have 2 questions
1. Is it possible to multiply an array by a number in TestStand?
I know there are some numeric functions available in TestStand but I don't know if like LabVIEW I can multiple ( subtract/add/divide...) all the elements of an array by a number
2. Let's say I want to pass a 1D array of numbers ( size 10) to a code module but I would like to just pass the first 5 elements . How can I do it in TestStand ? I have checked the array function but I couldn't find something like Array Subset?
Could you please help me with these questionIn TS 2012 and later they added some new array functions such as Min, Max, Split, Sort, etc... They also added the ability to do Locals.MyArray[4..8]. Which will give you elements 4 through 8 of the 0 indexed array.
As for the adding to each number I don't think that capability exists. If it did it would be something like Locals.MyArray + 100. It defnitely doesn't work in TS 2010.
Hope this helps,

Sort Array of References by Label-Name
I am developing on an DSC application with shared variables and alarming and events with a hugh amount of variables. Each variable is displayed on the front panel within tab controls. To reduce time and effort when expanding the variables I would like to arrange my references from the front panel by the label name. I've attached a part of the intialization of the front panel. There I have to manually expand each variable in the shared variable library, where the name of the variable has to be in the same order as the definition in the cluster.
My approach was to build an array of references of digital type and sort the references by the label name. Because the shared variables have the same name as the controls they would be in the same order and I also could dislaim the cluster of references.
maybe somebody can give my an hint.
Kind Regards,
Joachim

fp.jpg 982 KBHi Joachim,
use the standard "sort an array of cluster" approach!
Put the control label and the reference (in this order!) in a cluster, make an array of such clusters and sort the array. It will sort by the label and you can unbundle the reference in sorted order...
