[kepler-users] Kepler 2.3 and MATLAB

[Matt Jones]

Wade --

Matlab is a bit trickier than R because the linkage to Kepler uses JNI via
a shared library (dll on Windows) for matlab, whereas we use a shell
invocation for R. So, for it to work, both the class path has to be right
and the dll has to match the OS and architecture. I don't have Windows or
Matlab to test this on myself right now, but in the past the issue has been
simply getting the right dll to be invoked as the bridge over to matlab.
 If you haven't worked this out by Monday, I'll see if I can get a copy of
Matlab from NCEAS and try it myself.  The fact that Christopher is able to
run it with his Kepler 2.3 is good news. I think either Dan Crawl or Jianwu
Wang have successfully run it on 2.3 as well -- maybe they'll have some
insights.

problem is just related to the MatlabExpression actor, which is what I'm
particularly interested in using.

I can find on the web, that  "The operating system cannot run %1" is a
generic error that implies a path issue. Anything I can check regarding the
Kepler classpath or libraries come to mind?

specifically "C:\Program

operating system cannot run %1". Hope that points to a specific issue.

the -jni argument: $PTII/bin/vergil -jni. For details, see
