…an undocumented feature was added to the Matlab Profiler that enables monitoring memory usage.

?

Your problem may be due to a missing jdwp.dll library file, which is required by the Java debugger but missing from Matlab’s JRE distribution. See MathWorks technical solution 1-OVU1L. Possibly some other DLL is missing. Other reported problems with the agentlib that cause Matlab to fail to start were reported here. I briefly discuss this in section 1.6 of my book, by the way.

If you do learn anything new, please post a followup comment here, for the benefit of others.

Have you ever used jtimp to profile java memory inside matlab?
I added “-agentlib:tijmp” in the java.opts file, added the tijmp.dll directory path in librarypath.txt file but matlab does not start any more (OS is windows XP)
Thanks !
