LabVIEW and MATLAB

[ianhaigh]

That was easier than I thought - I found an old email I sent to my lecturer who was having the same problem - hope it helps!

"I found a solution to the Matlab Script problem - I have run the fix on the rig computer which now runs fine.

If you want to update yours then follow the instructions on

http://digital.ni.com/public.nsf/websearch/4475BC3CEB062C9586256D750058F14B?OpenDocument

By copying the new matscript.dll file you download from the site above into

C:\Program Files\National Instruments\LabVIEW 7.1\resource\script

it applies a patch which fixes the problem."

Thank you all for the replies

Now suddenly its working, so it leads me to this question : Do I need to open MATLAB before I run the vi ???

is there any particular order I need to do ???

Thanks

No, you do not need to have Matlab running first. I ran your VI on a machine that had LabVIEW 8.2 and Matlab 7.0.4 (might have been 7.0.5, not sure) and got no errors, once I removed the "clear all" command. I don't know what R2006a maps to in terms of a version number. You never provided what error you received, and that's probably because you never wired an error out cluster to the script node's error out cluster.

Ian: that document only applies to LabVIEW 7.1. The poster is running LabVIEW 8.0, as indicated in an earlier message.

Additional Information: If you try your code in LabVIEW 8.2 and use the Mathscript Node (just drop a Mathscript Node and copy your m-script there), it think it will give the same result as MATLAB. Mathscript converts a m-script file into LabVIEW code and executes it in LabVIEW. If you will create an EXE in the end, that would simplify a lot of your application. I don't know if you have other functions that is not in this thread, but it is worth a try.

I thought you'd like to know about that...
