• MathScript NaN initialize the array LV 8.6

  For those of us who bought LV 8.2 - 8.6 Mac OS Suite of Dev, the mathscript module won't boot has a table with NaN.

  It's

  c = Nan (m, n)

  and

  repmat (NaN, m, n)

  are broken.

  The only work around I can find is to replace a number, for example '0 ':

  InT = repmat(0,m,n); InT (= NaN;)

  Would appreciate any other workaround to create an m x n array of NaN.

  Hi wjdwyer,

  This has been fixed in more recent versions of MathScript, but for older versions, another workaround potential that I could meet you multiply nan by a table that already exists (see below). I know that's not ideal, but if all goes well it will at least give you an alternative.

  A = nan * repmat(1,m,n);

• difference between mathscript and matlabscript

  Hi iam new to labview and learning n do labview project

  What is the difference between mathscript and matlabscript

  I want to do the simulation using matlab

  How can I do

  If one suggests this

  Please answer and provide assistance so that I will perform my project...

  With the LabVIEW MathScript node, the blue rectangular region, you
  can run scripts from files ".m" of your graph (known as LabVIEW programs
  virtual instruments or screw). You can use the MathScript node

  to insert text algorithms in a VI and then use the LabVIEW
  environment of graphical programming to instrument the scripts by adding
  buttons, sliders, buttons, graphics, and other user controls and
  indicators.

• If/else statement in the MathScript node

  Hi johndoe.

  Thank you for contacting National instruments.

  I would like to highlight a number of items which you may find useful for the implementation of an if-else statement in a MathScript node.  The first is a book white tutorial, which the second part explains how to use LabVIEW MathScript node. The second is an article describing the required syntax to write functions and scripts in the MathScript node, including instructions for the use of the If-Else statements.

  I hope that these help. Please let me know if you need additional assistance.

  Kind regards

• Is it possible to print the mathscript with color-coding text node?

  MathScript nodes lie down, I need to be able to make temporary annotations on paper.  Currently, the only way I can find to print the MathScript node is by screen capture and printing an image.

  While I can copy the text and put it in a word processing program, I would lose all the useful color coding.

  Y at - it a tip to copy as text and preserve color-coding?

  Download and install the notebook of the programmer.

  Copy all the text of the Mathscript node and paste it into Notepad to the programmer.

  In the menu bar - view - check syntax highlighting

  In the menu bar - display - regime change - select Matlab

  In the menu - Tools - Options - fonts and colors - bar you can select a larger font size

  (Although my vision is corrected to 20/10 and I have a lot of difficulty to read tiny fonts in the Mathscript node on a screen high resolution after a couple of hours.)

  This software is free and has a full set of features for serious programmers.

• Array of strings 1 d out of MathScript node

  I use arrays of cells inside a MathScript node and want to display an array of strings D 1.  I can't get output with this data type by selecting a column of string elements.  He seems to treat the strings as arrays of characters that are extremely difficult to work with.

  I've seen references 2008 who say that MathScript nodes cannot not out of arrays of strings,

  Is this always true?  Is there an example of how to get a string or some kind of workaround?

  My boss came up with a way to do it, as shown in the attached VI.

  The problem is that your "out" is not defined, as executed in your script. Maybe it's what you want instead

  out = - 1; % define value as default for the

  If in == 7

  out = 6;

• In 2012 LabVIEW MathScript RT module does not work

  Hi all

  I recently installed LabVIEW 2012 in my PC with Windows 7. However, Mathscript does not at all. It says "an internal error has occurred in the MathScript RT Module.  Restart LabVIEW and try again.  If the error persists, reinstall the MathScript RT Module. "I did it, but still does not work. It is said further than Mathscript is missing or not installed", but I have installed. What the problem would be, please?

  Have you been able to verify the installation and activation in the License Manager OR? It should say enabled for this computer and have a green square like this:

  

• "print" command in Mathscript recording is not the plots in BMP format!

  Hi guys,.

  I am creating a vi that automatically generates a pdf for my project report. I found a way to record the report directly in pdf format (in other words, I have 'print' my report to a (PDFCreator) Virtual PDF printer that saves the file in a specific folder with the date/time under his name.) "So, this was the first step to make the automatic procedure).

  I'm stuck in the next step, which is adding to the report no graphics bad appearance of labview, but the plots of the victims of the Mathscript.

  Yes, after you have added as input 'a' my data to the mathscript node, I use the following commands:

  Figure

  Plot (a)

  print the image

  Now, what is this sequence is to do a beautiful land of my data and then save it as "image.eps" in the default folder.

  However, the eps format is not at all useful to me because I can't import the plot with the 'Add Image to Report.vi '. This vi supports the formats BMP, GIF, WMF, EMF and JPG only.

  So, I want to save as BMP mathscript plot. It's supposed to be possible, but I have not been able to find a way. Using the command 'Print' for Labview Mathscript 2011 reads as follows:

  http://zone.NI.com/reference/en-XX/help/373123B-01/lvtextmath/msfunc_print/

  Syntax

  
  

  print

  Print (a)

  Print (file)

  printing (, file)

  Description

  
  

  Print the trace window, or save it in a file in BMP or EPS format. If the trace to save window is a plot of the image or a 3D terrain, the file must be in BMP format. Other types of plots, formats BMP and EPS are supported.

  There is no way for me to choose what format I want, and it automatically selects the eps. If I use the command

  print image.bmp

  It gives me an error. So adding the endpoint .bmp is not the way to go.

  Overall, it is essential for me to export the plot in BMP format (in order to import it into the generation of report), but I can't find a way, althouth it is supposed to work.

  Any ideas?

  Thank you

  PS. I run Labview 2011 SP1

  Hello

  You must use the following command

  Print ('test.bmp')

  Instead of

  print test.bmp

• How to feed a cluster in the mathscript?

  Hi all

  I'm trying to feed a cluster in the mathscript. I found that, if the name of the element in the cluster has no spaces or special characters, it works fine. But it does not work if the name of the cluster components have special characters. That's how Mathscript designed? No work around here?

  Hey dragondiver,

  We hope that you do well today. This document overviews the intended use and the behavior of data with MathScript types.

  Transmission of data in and out of the node MathScript (MathScript RT Module)

  http://zone.NI.com/reference/en-XX/help/373123C-01/lvtextmathmain/ms_passing_data_lv_mathscript/

  So, to answer your question more specifically, the rule for naming elements within a cluster in the node is,

  "You have to tag individual items in the cluster. The labels must begin with an alphabetic character and can contain only alphanumeric characters and underscores, no spaces. »

  It must explain the behavior you're seeing with your code!

• Create an executable by mathscript or from the Windows command window

  Hello

  I have a lot of screws that must be built into executables. So, I think to write a script to save time.

  Windows MathScript looks a lot like the command window in MATLAB, so I wonder if there is a way to create executable files using mathscript?

  Or is it possible to build from the windows command window?

  Thanks for your reply and have a nice day.

  Kind regards

  You can use the tools in the palette of constructor calls write a LabVIEW program to automate the construction of applications.

  (Somehow I don't understand not what you want. Building is usually negligible compared to write the program or the configuration of the build).

• Mathscript in LabView 8.5.1 3D paintings

  Hello

  Can the Mathscript in Labview 8.5.1 feature manage pictures 3D and process the data accordingly? All berries are generated in the Matlab script, analyzed and processed as required 1 d numbers and individual issued to Labview.

  Thank you.

  Hello

  At that time, MathScript can not handle 3D tables (either internally or when interfacing with LabVIEW).  We are aware of the limitation and would like to support in a future version.  Is it possible to achieve what you want with several 2D arrays?

• Improved speed for the LabVIEW MathScript calculation

  I use a MathScript node to perform calculations on a sbRIO FPGA module and the speed of these calculations is critical.  What are some ways to improve the speed of calculations and y at - it a faster way to make calculations of MathScript matrix?  If I belong the MathScript in a Subvi it will improve the speed of calculations?

  Thanks for any ideas

  Please look at the VI attached. She is your original code ".m", my changes to your ".m" and G code equivalent to the updated code ".m". First, let me describe the numbers that I've seen on a cRIO 9012 for each of the three approaches.

  I ran to each of the three approaches for the hundreds of iterations, ignored the first 30 iterations to allow allocations of memory (which caused a huge spike in runtime performance about the RT), then took the average operation time for each iteration of the loop for the remaining iterations

  Original M: 485 msec/iteration

  Updated M: 276 MS/iteration

  G: ms 166/iteration

  The changes I made to your code ".m" are:

  (1) added; at the end of each line to remove output (used for debugging)

  (2) left random code generation - used whitenoise (seems like that is what you did)

  (3) turn on the type of data highlighting the function. Noticed that the majority of data was cast in the complex, although that did not seem like you need the complex domain. The source has been function sqrt. Changed using real (sqrt (...))

  This improvement in performance by more than 40%. I believe that more can be pressed if you follow the documentation - MathScript wrote for real-time Applications.

  Then I took the MathScript you and equivalent written G leaving the algorithm as it is. This gave us the improvement of the performance of another 40 per cent in the G. updated the it is a known issue that on slow controllers, MathScript adds a penalty of 2 x to g equivalent. We are investigating this issue and may be able to fix it in a future release.

  If you are profiling the G code, you will notice that most of the time we spend in the multiplication of matrices. Unless rethink you your algorithm, I doubt that this can further improve.

  Let me know if you have any questions

  Kind regards

• How to share a variable between the Mathscript Windows and a Mathscript node

  Hello

  I'm trying to share (just) a variable between the Mathscript Windows and a Mathscript node. I don't know why, but the use of the "global" Matlab function makes the mathscript node output formats change.

  I'm looking for a "Mathscript RT V9.0.1 module" as it may seem, there is. French technical support have some difficulty to find...

  Hi patrick33,.

  The code that you have attached should not report an error, so it seems that something has gone wrong with your installation of MathScript. My best guess is that it is the problem that is described in this knowledge base article. Your signature says that you use f3 patch, which is a good start. But the KB lists some other steps to take when you see errors about MathScript, impossible to compile. Can you try the procedure described in the article and let us know if that fixes the problem?

  Thank you

• Change the working directory of the MathScript node in the working directory of the VI in which the node is added

  Hello

  I want to automatically change the working directory of the node Mathscript in a VI in the working directory of the VI, while I don't have to specify every time where is my file ".m", as most likely, it will be in the same folder as the VI.
