• Spend the MATLAB data types 'cell' between MATLAB script nodes in LabView?

  Hi all

  I need to pass a variable of data type of cell of a MATLAB script node in LabView to another, but the cell is not listed as a data type 'exit' in the script node.

  Is it possible to do without converting them into a 2D array?  Each column of my cell has a different number of lines...

  Thank you!

  Mike

  Too bad...

  Rather than use a typical LabView, I just say

  assignin ('basic', ' varname', varvalue ");

  in the first script and varname called from the second node to get my cell.

  Easy... duh leaving here if anyone has the same issue in the future.

• 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
  versioned. (i.e.
  installed on the network server, but not in the local hard disk).

  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

• Features of the Matlab script node

  Comparing only the specific features that overlap of Matlab and Labview, is there an advantage for the latter to be able to run blocks in parallel? What exactly is the purpose of the Matlab script node in Labview?

  MathScript can be deployed on real-time hardware (if that is the question). I don't know about the others.

• 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.

  He worked

• Display problems using Firefox with Windows 7, 64-bit

  Hi support them

  I have a new desktop computer running Windows 7, 64 bit.
  When I use Firefox version 3.6.8 to view my Web site, it displays everything out of alignment.
  If I use IE 8.0 it shows very well.
  If I use my laptop which is running Win XP site displays fine with IE 8.0 and Firefox.
  So I guess it may be a problem with Win 7, 64 bit and Firefox work well together.
  Is there a ready solution to help solve this problem or I have to wait until Firefox came out in a 64-bit version?

  It's almost as if the extra percentage signs stripped the first time and the second time I did of this chain, they mistake.

  In the example that you have posted, it seems that you could use strcpy() instead of the sprintf() function. strcpy() would not seek to interpret the content of the string in the same way.

• Problem of Windows with Action Scripts run from a Panel

  I created a panel that has shortcuts for Menu items and tools. I have also two buttons on my slab that run scripts that were created with Actions. I tested these two scripts with the ExtendScript Toolkit for both Mac and windows.

  Both scripts do not run on some computers in the window, but they do on others. It seems that the problem more with 7 of the window then in any other operating system, but it is not universal.

  I am at a loss on how to get hurt this problem. Machine window 7, I'm testing on runs the script without any problems, but some users of my panels have the problem above.

  Any ideas?

  Thanks in advance - Sam

  Action handler code looks like it's a step to play a shadow of action which lies in a defined action named SmileixPix.

  If you added that action shadow action value saved SmilePix the action defined and distributed the action defined in the package.

  If users have an action set SmilePix and you loaded the update action defined as a part of you install. Users can end up with two responsible actions named sets SmilePix one containing the action of the shadow and the other without the Sdade action.  I don't know what would happen if your panels has been used and there was a prior action set SmilePix which is not the action of the shadow.  Make sure that defective computers do not list Action Games named SmilePix twon

  Hello

  Webcam works fine - with CAM software but not with ICQ.
  When I take a glance in the Panel of configuration/Scanner/cameras it isn´t

  Can someone help me please?

  Please, I beg you!

  Hello

  One of my friends told me that he has disabled the software of the Webcam at MSCONFIG startup and after that he has no problem using cam with other applications. You can try to test it.

• labview MATLAB script prevents the execution of several times.

  I have a code for communication series in matlab, I want to use in labview for graphical interface easier and better design. for this I used the matlab script node in labview. It seems that labview continue executing the script of matlab, but I want to labview to execute only once.is he sort of to do?

  I don't see how that can occur if you run the VI in "continuous" mode

• 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.
