Problems installing PCT 5.1 (2011a) with Matlab 2012b

Hi everybody!

I just installed the latest version of Matlab. Now within the several toolboxes I want to use I need the Parallel Computing Toolbox not to be newer than 5.1 (thats what my cluster admin told me). Now after installing the PCT and checking with "ver" command I find it listed. But simple "matlabpool" gives an error:

Error using matlabpool (line 125) Error: File: schema.m Line: 13 Column: 8 Arguments to IMPORT must either end with ".*" or else specify a fully qualified class name: "com.mathworks.toolbox.distcomp.workunit.WorkUnit" fails this test.

What does this tell me? I dont know, sorry.

Any ideas ? Thank you !

Never ever mix a toolbox from a different release than the MATLAB version. Sorry, but your installation is likely now really damaged and I suggest to uninstall everything. Don't try "repairing" it.

"Parallel Computing Toolbox not to be newer than 5.1 (thats what my cluster admin told me)."

I don't knoww why that is, but assuming there is a good reason, then you need to install all products on R2011a level.

Ok. Thanks for reminding me on this "golden rule"!

It seems that simple uninstalling is also not that easy after having mixed up the installations.

I'll change to 2011a in total now. Thank you.

Glad I could help. And tell this admin to modify the advice towards future users. This is "muda" at its best!
