[kepler-users] Invoking MATLAB interface

[Peter Li]

Hi,

Yes, both PATH environment variables are right and I can run Matlab from the
command prompt.

The first error window that pops up is a javaw.exe - Entry Point Not Found
error that says "The procedure entry point mxSetName could not be located in
the dynamic link library libmx.dll." which is then followed by the message I
posted above. This message only occurs the first time I attempt to run the
workflow. Subsequent tries goes straight the error message posted above.

I'm running Matlab 7.8.0.347 R2009a version.

Thanks,

Peter
