  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;

• 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?

• MatLab Script can work in multi-cores?

  Whe LabVIEW going through a 'Matlab Script' Matlab code, the part "Matlab Script" works in a single-threaded or multithreaded mode? It uses the ActiveX to communicate with Matlab, so I guess that's the only thread?

  I have a LabVIEW code that needs to call a ".m" file. I wonder if the execution of the program will be greatly improved if I convert the file ".m" in a .dll file to eliminate the need to activate the server Matlab a lot of time.

  You are right in your assumption that the MATLAB Script nodes are running single-threaded. A single script will be able to run at a time.

  You may be able to improve performance to build in a DLL, but you should test on your machine to know how much. I have not really thing this would be too great. A building in separate maybe dll code you can also improve performance by allowing for parallelism, you could call DLLs separated in different threads, I think.

  Another option would be to use the MathScript node - which allows for parallelization.

• MathScript node: an error internal mathscript: 64-bit LabVIEW 2009

  Hi people.

  I have an installation now LabVIEW 2009 9.03f, Vision and Advanced Signal Processing Toolkit, all 64-bit versions on a new computer, so that I can convert a code from 32 to 64-bit.

  I tell myself that I will address the errors one by one and this is the first.  I have a VI with mathscript node and the VI, who instructed and ran very well in the 32-bit environment, is now broken and giving the error "mathscript node: a mathscript internal error."  My main concern - is mathscript unsupported in LabVIEW 64-bit right now?

  I enclose the VI.  Any ideas are appreciated.  I need to get this working.

  In addition, NEITHER is there a special forum of 64-bit we should publish in the future, or create to post on?

  Sincerely,

  Don

  LabVIEW MathScript is a language based on text that you can use to write scripts and functions. You can process the scripts using LabVIEW MathScript in the Window of LabVIEW MathScript or a MathScript node. When you create a LabVIEW MathScript, you use data types supported.

  The MathScript syntax is intuitive and logical syntax essentially based on the standard mathematical and computer programming terms, mandate of widespread and common use truncation or descriptive abbreviations and concatenations of standardized terms. The Window of LabVIEW MathScript and MathScript nodes are able to process files that you create using the MathScript current syntax and, for backward compatibility, files that you created using legacy MathScript syntaxes. The Window of LabVIEW MathScript and nodes MathScript can also process some of your files using other textual syntaxes, such as files that you created by using the MATLAB® software. Because the MathScript RT Module engine is used to treat the scripts in the Window of LabVIEW MathScript and MathScript node, and the MathScript RT Module engine can't stand any of the syntaxes, not all existing text scripts are supported.

  (64-bit LabVIEW) LabVIEW MathScript is not supported in LabVIEW (64-bit).

• Need help on how to create the transformation of the Park by using the MathScript node?

  Hello

  I want to generate a transformation of the Park by using the MathScript node. But there is an error message which confused me. Please can someone help me to have a look of my program? Thank you!

  The error message is "error-90011 occurred in error in the function mail to line 1.  The sizes of the input matrices are incompatible.
  Check that the matrices have the same size or one is a scalar.

  Possible reasons:

  LabVIEW: Sizes of the input matrices are incompatible.  Check that the matrices have the same size or that one is a scalar".

  Hello

  The problem is that all of your entries to the MathScript node are vectors.  All entries of the vector to the MathScript node becomes vector lines.  A multiplication of two vectors lines generates a size mismatch error.  If you really want a scalar of this multiplication of output (by calculating the dot product of vectors), then you have to bring your 'a', 'b' and 'c' vectors or your vector of 'x '.  If you want everything just multiply your elementwise vectors and produce an output vector, you must use the elementwise multiplication operator '. *' (time point).  Use this operator between your 'a', 'b' and 'c' vectors and your calculation of fishing.  For example, on your first line,
  d = (2/3)*a.*(sin(x))+(2/3)*b.*(sin(x-(2*pi/3)))+(2/3)*c.*(sin(x+(2*pi/3)));

  Don't forget to also change your output to a 1 d of DBL array variables.  You can do this by right-clicking on the output variable and selecting "Choose Data Type."

• mathscript node Mac could not compile

  I just installed LabView 2009 SP1 on Mac OS X (Snow Leopard), as well as MathScript, who can't do much beyond a simple assignment.

  A simple if-else structure will work if it performs only scalar assignments, drunk, trying to create a simple 1 d of table within a node structure MathScript (x = 1:1:10) causes VI to break with the error ' MathScript node: VI failed to meet. "

  Similarly, try the following commands in a MathScript window all give "error at line 0: an internal error occurred during the processing of this MathScript.» Contact National Instruments with the MathScript you used. »

  t = 1:1:5

  t = linspace (1,5,1)

  help linspace

  It's not yet the command help. The only thing that works is something like x = 5 or x = sin (2.2 * pi).

  I am aware of these two articles, or which is applicable for Mac or for 2009 SP1:

  59AH3P4A Knowledge Base: Causes of failure Compiler Error with MathScript node

  553C13WI knowledge base: Detection screw instantiation corrupt and MathScript node failed to meet Er...

  The second section offers a few folders to delete, which I've tried. The other does not exist on install Mac. Needless to say that the utility to find corrupted instantiations is not useful here.

  Thanks in advance for your suggestions.

  Inches,

  Is that you improved in 2009 SP1 MathScript RT? The 2009 version of MathScript won't work with LabVIEW 2009 SP1.

• 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.

  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

• E-mail message full automatic download (incl. attachment) on iPad - so I can work offline on emails

  I would totally and automatically download my emails (including attachments) when connected to the network (WiFi or 4 G), so that I can work on my emails when 'off line' (i.e., plane). Now, I often get the error message 'message not downloaded from the server. Please your audience.

  There is no setting to do that automatically - it can vary on the type of network, you're on - some users have reported all their emails downloaded - others indicated only small do - you use a POP or IMAP account type?

  Another option is to consider an application like Documents 5 - but you must always manually download and store e-mail messages and attachments you can work later

  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

• DAQmx property in event node can % 27T be update

  I want to update the node property of DAQmx event to update dynamically the value, but only 1 of the 2 property node can be updated "DAQmx is task Done.vi", the whole could be triged normally.

  As shown in the photo below: report cyclic case can be triged and run, but the value of property not upgrade vi DAQmx. well frequency one normally.

  

  

  

  The answer is probably more strange than you expect.  It turns out that the two impulses of the synchronization frequency and duty cycle parameters are also privileged.  (I believe that the same kind of asymmetry applies when you set a pulse with high and low time).

  Frequency Gets the privilege in this sense the pulses of timing is changed only when a frequency value is written.  In order to change the operating factor, you need to get a property node DAQmx Channel, expose the properties of duty cycle and frequency and write to both of them.  You don't need to change the * value * you write in the property of frequency, but you * need to write for her.   Given that written node property follow these up and down, it is important to have the property of cyclical report above the frequency property.

  Here is a more complete article.

• is it possible to use a file refnum as mathscript node entry

  Hello world

  I started using the LV and mathscript recently. A problem confuses me a lot.  It's

  Is it possible to use a file refnum as the entry or exit of the mathscript node? A picture is attached for your reference.

  Thank you very much!

  Gary

  What would you hope to do with the reference?  The Mathscript node is not a file of reading ability.  You must read the file and transmitting the data in the Mathscript node.

  EDIT: I was wrong.  You must use the functions fopen and fclose inside the MathScript node to be able to read a file inside.
