Hi, do you receive any error from the Matlab script box error out (in labview) on the PC where it doesn't work?
In my PC, LV7.1 and matlab 6.5 (R13) everything works, I don't see matlab command window popping up, but script works well.
Could it be related to matlab working folder or something like that?
Labview calls matlab via activeX, so what works in matlab should work well in labview matlab script formulas too, if matlab is correctly installed (with ActiveX correctly registered).
Also take a look at this document:
How Can I Resolve MATLAB and Xmath Script Node Issues in LabVIEW?Ciao.
