[kepler-users] Invoking MATLAB interface

[Peter Li]

Hi all,

I'm trying to use the MATLAB actor, but I get this error message when I try
to run it. I'm running on windows XP and I've set the environment variables
to include the MATLAB bin and its win32 folder. It says that it cant find
the ptmatlab shared library but I can see ptmatlab.dll file in the
Kepler-1.0.0\lib folder. I'm fairly new at Kepler, so please excuse me if
this is a dumb question.

ptolemy.kernel.util.IllegalActionException: There was a problem invoking the
Ptolemy II Matlab interface.
The interface has been tested under Windows and Linux.
The interface requires that Matlab be installed on the local machine and
that the ptmatlab shared library available.
Refer to $PTII/ptolemy/matlab/makefile for more information.
