           Summary: Mac OS X: Matlab Actors fail in Kepler.app
           Product: Kepler

          Platform: Macintosh
        OS/Version: MacOS X 10.6.x

Models that use the Matlab interface fail when started under Mac OS X 
by double clicking on Kepler.app.

This is a new Mac running Mac OS X 10.7.

I had to make some changes to Matlab interface, these should be folded
into the Kepler-2.3 tree.

The problem is that in the devel tree, 
ant run-only was failing with:

ptolemy.kernel.util.IllegalActionException: .MatlabExpression.MatlabExpression:
ptolemy.kernel.util.IllegalActionException: Token 0.0 is of type double
  in .MatlabExpression.MatlabExpression

I fixed this in

New Revision: 61797

Modified:
   trunk/ptolemy/matlab/Engine.java
   trunk/ptolemy/matlab/Expression.java
Log:
Better error messages if time and iteration cannot be set.  Properly handle
DoubleToken and IntToken in Engine.put().  It is a mystery as to why this bug
did appear before.

However, with Kepler-2.3 rc1, I'm not even getting that far.
When I run the SDF MatlabExpression model, I get:

ptolemy.kernel.util.IllegalActionException: matlabEngine.open(null) : can't
find Matlab engine. Try starting Matlab by hand as an application to verify
that Matlab is set up properly and the license is correct. Under Windows, try
running "matlab /regserver", the Matlab C API communicates with Matlab via COM,
and apparently the COM interface is not automatically registered when Matlab is
installed. Under Linux and other types of UNIX, csh must be installed in
/bin/csh.

The Console application reports:

[null] matlab: Command not found.

However, the matlab directory is in my path, see
