[kepler-users] Kepler 2.3 and MATLAB

Sat Apr 21 13:48:07 PDT 2012

I can run the MatlabExpression workflow with Kepler 2.3 on
WinXP SP3 (32bit) using Matlab 2009A and Java 1.6.0_31-b05.

Your PATH looks ok (assuming you installed Matlab in C:\ and
not the default C:\Program Files). It's possible that ptmatlab.dll
is not compatible with newer versions of Matlab. You can find
instructions on building ptmatlab.dll here:
