• Error 1050 trying to use load 'filename' in matlab script node

  Hello

  I get error 1050 when Labview is trying to load a text via the node of matlab script file.

  I have all ready checked for her on this forum and google but found nothing. I also did this: http://digital.ni.com/public.nsf/allkb/2B3FF46C8512C4F786256CF30071BE53 and tried to use dlmread and much more.

  The thing is that I need the node matlab script for reading a txt file that Labview made a chart with 1 single table, draw the it and export a jpg image. I can't really use the 'export picture' or 'get image' function for cause of Labview, I need the whole route chart (these functions only take a snapshot of it when they are run).

  It's my code I use:

  Data = Load ('file');

  VPP = (Data (1:2000,1));

  XSIZE = (1/2000);

  Plot (0.0005:0.0005:1 VPP);

  axis ([1 0 5 - 5]);

  print ('-images ', 'graph.jpg');

  The usual matlab load to load txt files and print to print the jpeg format. The code works in matlab, but not in labview

  And Yes, I use windows 7 and legal versions of matlab r2009b and Labview 2009

  Hehe, I thought about it

  Path must be converted to a string and skip the ' in the file.

• dynamic import of video files on execution

  Hello world
  
  I'm adjusting a lingocode to import video files instead of images in a cast. So that users can edit the video by playing one of their own videos and save the reference in a castlib.
  But the scene shows a picture of windows media indicating that it is a member of the windows media distribution only but do not actually play a video as it does not contain the path to the video file
  
  The new code;
  On MouseDown
  FIO = xtra("FileIO").new)
  file = fio.displayOpen)
  FIO = Sub
  newMember = new (#windowsmedia)
  newMember.fileName = file
  Sprite (3) .member newMember =
  newMember.duplicate (52, 'media')
  end
  
  I use the last line (newMember.duplicate (52, 'media') to copy the cast member newly created in external cast (media) and specific member number (52)) Such external distribution containing the imported media reference can be saved by a Save"" button. And be accesed by about 9 other movies.
  
  
  What I'm missing here to run the dynamic import of video files? pointers?
  

  > On MouseDown
  > fio = xtra("FileIO").new)
  > file = fio.displayOpen)
  > fio = Sub
  > newMember = new (#windowsmedia)
  > newMember.fileName = file

  > end

  Works for me - with the exception of the duplication of Member. As suggested in the
  another forum you posted to, it would be better * not * use keywords like
  names of variables (such as 'file' and "newMember").
  It is unclear why you create a new Member in castLib (1) and link to
  Sprite (3) to duplicate and then to a different castLib. Why not
  you start with a member of the #windowsMedia location 52 of castLib ("media") and
  simply change its name property to file?
  --
  on mouseDown me
  tMember = member (52, 'media')
  If tMember.type = #empty then
  tMember = _movie.newMember (#windowsMedia, tMember)
  -tMember.name = "WMV".
  end if
  FIO = xtra("FileIO").new)
  tFile = fio.displayOpen)
  FIO = EMPTY
  tMember.fileName tFile =
  Sprite (3) .member tMember =
  end

• MATLAB script node error: 1046

  Hello world

  I now use Labview for data acquisition and want to use MATLAB

  I have some problems get MATLAB script to function properly. The
  It is:

  Whenever I tried to run the program, Labview gave me the following
  error:

  "Error 1046: Labview does not initialize the script server, make sure that the server software is.

  However, MATLAB is installed in the PC. I think that the reason of
  This error is that I'm using a PC based campus University. I got into this PC MATLAB is a network

  Is that what I can do to work around this error?

  Kind regards

  Hi hykwei,

  Unfortunately, it is not possible to obtain the MATLAB Script nodes to work
  LabVIEW under your current network configuration. So that the
  Node MATLAB Script to work properly, it takes that MATLAB is
  installed on the same machine as LabVIEW. This means that you will need
  either install MATLAB on the local computer on which you apply
  LabVIEW or you need install and use LabVIEW in the same
  Server computer where MATLAB is installed. Function of MATLAB
  feature, you may be able to make some sort of minimum installation on the
  local machine that adds MATLAB to your registry and program files list,
  but who sends you right to the copy of MATLAB on the network.
  However, I am not aware if it is still an option or how you could go
  on the implementation of this scheme, so if you are interested, I would contact with
  MATLAB for more on this topic.

  Kind regards

• MathScript instability with large Matlab scripts? (Labview 8.5.1)

  Hello

  I the student of LabView 8.5.1 version and experiences a lot of instability when you use Mathscript in Labview (the Mathscript block or the Mathscript window), but only when it comes to the larger scripts. The Matlab script is about 250 lines long and 16 KB of size and in this framework, are seven large paintings (six 14 x 8, built at the beginning and a 1000 x 9 which is built in a loop for, so increases with each iteration until 1000 lines). I find that whenever I have modify the script in the Mathscript node or the Mathscript window will freeze and hang for at least 10 minutes, sometimes totally crashing Labview Labview. As I wrote the script in Matlab, I'll have to debug in Labview and know what commands in Matlab do not work in Mathscript/Labview, so it's obviously pretty infuriating to have the program regularly hang for 10 minutes at a time.

  The computer I use is a desktop Packard Bell 5 year with 768 MB of Ram (less 32 MB integrated graphics card), running XP Pro. The processor is an Intel Celeron 2.6 GHz. I appreciate this isn't the best specced machine ever, but at the time it was all I could afford!

  Is this common suspended a little problem with Labview and Mathscript file ".m" large, or is manipulation - this purely down to my old computer?

  Thank you much for the help.

  Hello

  The delay that you experience is a problem with the big scripts in MathScript.  The delay increases exponentially with the length of the script.  For this reason, we recommend disaggregation great scripts and files ".m" in rooms separated by about 40 lines.  On faster computers, you can find the acceptable period for up to 100 lines.

• Running MatLab script

  Hi guys!

  I use TestStand to connect a bunch of data and save them as binary files. When the test is finished, I would like to start a matlab script. For the moment I do it manually, just open MatLab and change the path used by the script to find the particular set of binaries to test.

  What I understand you can use MathScript with the basic package.

  I requires nothing more of Matlab open / running a script in the background at a time given in the test. Could it be done by using a system call and just passing the path as a parameter to a LabView VI?

  Any IDE for what is the best approach?

  Thank you for your time!

  Ah, I understand now. Yes, the basic edition doesn't have the Matlab script node. In this case, you can use Exec System to simply call the Matlab command line. Matlab documentation contains various switches to it.

• error 1050 with matlab script

  Hi, i ' v built a vi what sampling record and playback of audio files, I also added matlab script for data analysis.

  the script tested in matlab and matlab works great, when im trying to use it in labview, I get an error when running sciprt matlab. "Error with the help of griddedInterpolant... »

  I think the error takes place whe trying to run the command: "Sigitp = interp1 (clptv, clpsig, tv,"linear")"; "."

  Furthermore, I can not understand how to read the saved filed when the loop is complete.

  I don't know what the problem is.

• Using the table as a MATLAB script for entry into a Subvi - labview crashes

  Hello

  I have problems in creating a Subvi, which includes a matlab file that has a table as input.

  I created a VI, who runs a simple matlab script, with a table as an input and a table as output. It worked well, until I assigned the terminals in order to to use as a Subvi.

  After that the terminals have been assigned, labview crashes instantly when you run the file.

  I also created a VI to test the Subvi, but I couldn't make it work at all, labview always crashed...

  Does anyone know a solution to my problem? They only thing I can think is to not use it as a Subvi, but then my master file will get huge as all the matlab code would be in there...

  attached are two files, so that you can better understand my problem. (test_... is the main file)

  any help will be greatly appreciated!

  Edit: I'm using labview in 2013 with windows 7 and matlab 2014

  Hey, Jarno,.

  This is indeed a bug, unfortunately. Currently followed by using identification number of the 446431 cause. The question arise when moving from an array of doubles in the Script node. The only 'solution' at the present time is to use an array of singles instead. We are currently looking to identify a fix.

• Myrio and Matlab script

  Hello

  I control my physical robot with labview and my rio. I also have a matlab (m.file) code that uses it the Robotics Toolbox in Matlab. I would like to add this m.file to my labview program. Can I create a matlab script in the program labview and matlab code inside and deploy code to myrio? It will work in this case?

  AFAIK, the nodes in script call script software MATLAB server to run scripts written in MATLAB language syntax. But I don't know about adding my rio to the loop.

  Thanks for the reply.

  I also later get to know that this can be done by establishing communication between Matlab and myrio wifi.

• Output of a Matlab script

  Hello everyone

  I work on a project for school and had a question regarding the output of a Matlab Script node. I have data that is stored in the form T(:,:,i) is 3D data which are calculated in the script.

  The main thing I want to do is output, so I can graph on a façade of Labview. I want to display an image in 2d with a third dimension represented as points on the 2d image. (2d space with the 3rd dimension in temperature).

  It would not make sense why I am doing this in Labview but I have a set built for Labview GUI and it is an extract of things I want to show. I included a file for special graphics, I am trying to show in the end.

  I'm sorry I am still learning the ropes of Labview.

  Hi Jakeyboy1,

  Here is a link that shows how to send a table to 3 dimensions of LabVIEW, but you should be able to easily change the schema in the article to go through the process.  In the article, the first table of auto-index 3D of the sample code to assign a T(:,:,i) within the script environment.  LabVIEW then uses another script node to deal with 3-Dimensional table built.

  You can enable this process.  Off the first script thread knot out the length of the 3rd dimension and which feed the Terminal N of a loop for.  In the place the script node loop that reads T(:,:,i) and outputs the 2D from the node table.  You can plug this on loop for and autoindexing should create the 3D chart in LabVIEW.  From terminal N is the length of the 3rd dimension.  The table resulting in LabVIEW must be identical.

• 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.

• Permission denied error when you use the Matlab script

  I have the following simple running a Matlab script in Labview.

  K = 5;
  Matrix = randn (4,4);
  matlab.io.saveVariablesToScript ('Parameters.m', {'K', 'Matrix'})

  the last command saves the variables 'K' and 'Matrix' in the m-settings file that I can then use to load the settings 'K' and 'Matrix' to a 'Control Design and Simulation Model'.

  When I run the now from Matlab everything works fine. When I run this LabVIEW so I get the following error:

  LabVIEW: An error has occurred during execution of the script. Error message from the server?: Error using matlab.io.saveVariablesToScript
  Parameters.m: Could not open the file: permission denied.

  I use Matlab 2015 and LAbview 2015 in a 64-bit windows computer 7.

  Any help would be really appreciated.

  For those who have the same permission denied errors, I found the solution.

  I had to specify the current working directory in the matlab script (this is the directory to which you saved your LAbview VI).

  For example, if you have saved your labview vi to C:\Example_Folder

  then you must add the following command in your matlab script node before the command that causes the error

  CD (' c:/Example_Folder')

  I hope this will help.

• May first open .arcutx scripted files directly without prelude envoys?

  I have a folder of scripted files exported from the prelude on a single computer and I would like to import into first on another computer that does not prelude.

  Is this possible?

  "A rough cut that is created in the prelude can be opened directly in Premiere Pro."

  which reminds me to use the prelude command > Send to premiere pro.  that would not help in your case. but I could be read wrong.

  then I thought, adobe has probably been a bit lazy and recycled project for prelude first pro folder... so I renamed the file .arcutx in a .prproj file. and it opened very well in first pro!  give that a go
