• Creating tables in a nested for loop

  Hi all.

  I was stuck in this problem for quite a while now and I still don't know how to continue. Some outside the entrance would be greatly appreciated!

  I'm doing the following:

  -Take an array of numbers, to check if they are within a certain range (e.g. between 2 and 4)

  -Build two new arrays: one with all the numbers that are inside the beach and the other with the rest.

  An additional condition is that the amount and value of the range conditions will change (for example, it could be between 2 and 4 only / 2, 4 AND 6 and 7 according to the entry)

  To treat this, I created two nested for loops - one that goes on a table that contains conditions of the beach and inside that actually go and check if the values are in the range. I think I did that part successfully, but the next part is confusing to me - how to actually create the tables separated within two loops for?

  My apologies if I did not explain it well. Another method to support this problem is I want to translate following LabVIEW:

  Ranges of table / / [1 5 7 10] exodus-> This means we want to divide numbers based on those who are in (1,2) and (4.5) against those who are not

  Table of values / / [2 3 6 11 3]

  EndOperationDelegate table / / array of values within the range
  Table outValues / / Array of values out of range

  for m = 1:size (ranges)

  for n = 1:size (values)
  If (THE NUMBER IS on the INSIDE of EACH RANGE)
  EndOperationDelegate = [EndOperationDelegate NEWNUMBER]
  on the other
  outValues = [outValues NEWNUMBER]
  end

  end
  end

  Sounds easy enough, but it gets so chaotic with Labview that I don't know what to do. I have attached a reference image - insertion in the array function is not in fact add to the table, it creates a new table. How can I save that for when the nested for the ends of the loop?

  I have seen a few examples with shift registers which lie in a loop and I couldn't successfully that transfers in my block diagram.

  Any help/direction would be greatly appreciated.

  Hello!

  See the following example to understand how you can create a table in the loop For

  

  In your case, you also can uce conditional terminal to create a table only when then located nearby. It makes the code much cleaner that the structures of the case

  Hope this helps, if not, let me know if I can help you!

• Capture of sequences of images - issues with nested for loops

  Hi all

  I've written a vi. to capture a number of images ("Image") and save these images, sent to a folder of my choice.  Each image is identified sequentially.  However, I would like to make a number of iterations ("run") of this capture sequence, such that each image file name would be "Filename (Run) _(Image_No).png", for example run 5, image 10 'Filename 5_10.png.  I tried a nested for loop for this but I have an error message 'Current asynchronous i/o Operation' (I have attached a printscreen).

  Can someone help me solve this problem?  Please find attached my vi.

  Sincere greetings and thanks,

  Miika

  Hi toto26,.

  Thank you for your response.  I solved the problem by using a sequence structure flat - file in the first image and all the treatment in the second.

  Kind regards

  The analysis is totally false. You operate processXML() should be like this:

  function processXML(e:Event):void
  {
            slideData = new Array();
            loader.removeEventListener(Event.COMPLETE, processXML);
            loader.removeEventListener(IOErrorEvent.IO_ERROR, loadError);
            myXML = new XML(e.target.data);
            voiceOver = myXML.@voice_over;
            startOffset = myXML.@start_offset;
            myXML_Container_Length = myXML.children().length();
            var node:XMLList;
            for (var j:Number = 0; j <= myXML_Container_Length - 1; j++)
            {
                      id_cont_array.push(myXML.containerss[j].@id);
                      node = myXML.containerss[j].children();
                      myXML_textField_Length = node.length();
                      for (var k:Number = 0; k <= myXML_textField_Length - 1; k++)
                      {
                                switch (node[k].name().toString())
                                {
                                          case "textfield":
                                                    trace(node[k].@id);

  Please do not raise the same question several times. The answer is always the same. Your data model is seriously wrong - and that's the reason why you can't get data from it.

  I know I won't have access to the LineNumber result with in second forloop because of the determination of the lexical scope.

  Far from assignment, I am unable to get the value of the number of the line itself.

• Create a directory tree: how to call a global function from inside a for loop

  Hello

  I am trying to create a workflow that will create a directory tree in vCenter.

  Concept:

  Basically, I am trying to execute nested for loops for each level of the tree to the caller a global tree.

  Problem:

  The 1st loop for works and creates the file 'Dev '.  The second loop for does not work with error message:

  [19:16:16.219 2013-06-27] [I] building Dev folder
  [19:16:16.474 2013-06-27] [I] directory Built: Dev

  I think it has to do with JavaScript not being not able to call a global function in a nested object (I'm not a programmer and don't know JavaScript, so don't shoot me on that :)

  Code: (will clean this up once I do work)

  var folderBase is ['Dev', 'DMZ', 'Prod', 'UAT'];.

  var folderT1 = ["servers", "Jobs"];

  var folderT2 = ['Window', 'Linux'];

  var folderT3 is ["Repo2', 'Repo3', 'Repo1', 'Repo4'];.

  var folderT4 is ["T1", "T2", "T3"];.

  Create the files folderBase level

  for (var i = 0, l = folderBase.length; i < l; i ++) {}

  var rootFolder = parentFolder;

  buildFolderTree (folderBase [i]);

  Create the files folderT1 level

  for (var j = 0, l = folderT1.length; j < l; j ++) {}

  var rootFolder = folderBase [i];

  buildFolderTree (folderT1 [j]);

  Create the files folderT2 level

  for (var k = 0, l = folderT2.length; k < l; k ++) {}

  var rootFolder = folderT1 [j];

  buildFolderTree (folderT2 [k]);

  Create the files folderT3 level

  var rootFolder = folderT2 [k];

  buildFolderTree (folderT3 [x]);

  Create the files folderT4 level

  for (var y = 0, l = folderT4.length; y < l; y ++) {}

  var rootFolder = folderT3 [x];

  buildFolderTree(folderT4[y]);

  }

  }

  function buildFolderTree (folderName) {}

  System.log ("Building folder" + folderName);

  rootFolder.createFolder (folderName);

  Hello

  The createFolder() method returns the object VcFolder to the folder just created, for the new file to be used immediately.  Here is how I modified the code:

  Create the files folderBase level
  for (var i = 0; i)
  var newBaseFolder = buildFolderTree (parentFolder, folderBase [i]);
  Create the files folderT1 level
  for (var j = 0; j)
  var newT1Folder = buildFolderTree (newBaseFolder, folderT1 [j]);
  Create the files folderT2 level
  for (var k = 0; k)
  var newT2Folder = buildFolderTree (newT1Folder, folderT2 [k]);
  Create the files folderT3 level
  for (var x = 0; x)
  var newT3Folder = buildFolderTree (newT2Folder, folderT3 [x]);
  Create the files folderT4 level
  for (var y = 0; y)
  var newT4Folder = buildFolderTree (newT3Folder, folderT4 [y]);
  }
  }
  }
  }
  }

  function buildFolderTree (parentFolderObj, folder_name) {}
  System.log ("Building folder" + folderName);
  var newFolder = parentFolderObj.createFolder (folderName);
  System.log ("directory of frame:" + folderName);
  return NewFolder;
  }

• For loops with the cursor line and indexing

  Hi all
  
  I have a question about the loops with the cursor, line and indexing.
  
  How can I scan via a cursor with an iterator?
  
  I would use an iterator as
  
  Whole LoopIndex;
  Whole LoopIndex2;
  
  for LoopIndex at the beginning of the cursor at the end of the cursor
  loop
  line =: cursor [LoopIndex];
  for LoopIndex2 of LoopIndex at the end of the cursor
  etc...
  end loop;
  
  I need to use an iterator because I need to use a nested for loop.
  
  
  
  OR
  
  
  How can I solve the following problem?
  
  Class name % ofClass average test Score
  1 Niobe 7 8 8.4
  1 alena 4 7 7.5
  1 9 7 8.9 Estia
  1 Lilly 10 8 9.8
  1 Sandra 6 8 8.3
  1 Melanie 8 8 8.1
  Nadia 2 8 3 4.4
  Sayuki 2 9 8 8.4
  Diasy 2 7 8 8.0
  Flower 2 7 8 6.5
  Diana 2 6 8 7.3
  3 Flora 7 8 5.8
  Sukiya 3 4 8 8.4
  Samantha 3 10 8 7.7
  Roxanne 3 7 8 6.9
  Eline 3 8 8 7.4
  
  I need to
  -By class, I need to recalculate each average people
  -By class, I need to calculate the % of class score (sum averages / people in the class)
  
  So it can be done in a nested for loop?
  Or do I just step by step?

  Well, based on this information it would be something like...

• parallel processing: for loop taking place

  Hallo,

  I have a loop 'for' runnin on this system: LabVIEW2009, windows7, intel i7.

  I wonder if and how I can tell to LabVIEW that he would be allowed to run different iterations of the loop at the same time (concurrently) on my processor with 8 cores.

  Now, it will execute the next iteration when it ended the previous, even one so is there no dependencies in iterations.

  I want to give a 'ownership' of the loop, which means that it can be "unfolded" for parallel execution.

  Thank you

  Pier

  pop up on for loop and select "configure interation Prallelism."

  Activate it.

  Wire a certain number to the new 'P' of entry to specify how many processors to spread it everywhere.

• for loop in formula node does not

  Hello

  I; m trying to use for loop in the node of the formula, but it is does not work. I want the output (y1) product value in certain range (a and d, and of course one is smaller than d). I ' do not use primitive labview since a and d are keep changing (both are variable). I tried to put "return 0;" after the y1 equation but the error popup.

  The issue of the loop works not because it gives the last value (I average would be ""). It does not begin with an (initial) value.

  Please help me how to solve this problem...

  Pls ignore other variables not used in the equation. Thank you!! A lot

  Your code works.

  

  But why you use loop?
  You get the last value, so you can get it in a single step with x correct;

  Also why you say that can not use primitives?
  If you use wire instead of terminals or local variable States values constant.

  Y1, y1_2, y1 3 is the same values calculated differently.

  

• parallel for loops does not

  I'm learning the multi - thread programming. To start, I use "parallel for loops" and I was surprised that it does not work. One - thread loop work a few times faster (depending on settings) that multi - thread. I don't know why, and it is my request to correct my Vi to work properly.

  A parallel FOR loop has an overhead for parallelization (split the problem, then go back the results, etc.). If the code is very fast, the overhead is proportionally larger. If the Subvi takes a long time to complete, the overhead of parallelization is insignificant. It is often not worthwhile to parallelize the loops with a very simple and fast code.

  You can find it in vi.lib\utilities. It is well known.

• For loop runs with the value of N unwired

  In this case will be a loop run connected to the loop N worthless? I have seen a few examples of the loop for run without a certain number of times set to be ran wired or for example a size of table or something like that.

  PauldePaor wrote:

  Here's a program I am and as you can see the image that the program runs without the loop N being wired. The program will run without problem

  As everyone else has said, you don't have to plug something on N.  If you wire up a table for loop for input "auto-index", the loop for will run automatically the smaller table size.

  Perhaps an example will help:

  

  This makes a loop on my table size (in this case, long of 5 elements).  On the edge of the loop for which resembles [] brackets, indicates that it is auto-indexé.  The loop should go through each item one at a time (1, then 2, then 3, then 4, then 5).

• Préallouée VI environment in paralleled for loop

  Hello

  I searched a bit and couldn't find that everything about this specific issue.

  If I have a Subvi in a parallelized for loop and the Subvi is set upon reentrant preallouee clone, the Subvi register also several characteristics of memory depending on the number of loop iteration For? My specific application is a Subvi containingvibration Analytisis screw using the previous data in their spread and filters.

• For loop creates 1 d data table

  Hello, I am building the circuit below, and I'm running into a lot of problems with the loop, creating a table 1 d of data from certain types of data such as the ERROR OUT and the VISA NAME of RESOURCE. I understand why it does this, but I only need the last value in the table (the value of the last iteration of the loop for). This is true for me for the error, resource name of visa, and I was thinking of using the Boolean value that indicates when the for loop.

  Is there a simple way to extract the last value in the table 1-D so that it is correct to pass along trails, VISA and ERROR type?

  You actually create a block diagram, not a circuit.  A circuit is an electrical system including devices and wires.

  If you right-click on the tunnel and choose disable indexing, then you get the value of the last iteration rather than a 1 d table.
