Upon execution of qsubcellfun in matlab 2012a I get the warning Warning: The RandStream.setDefaultStream static method will be removed in a future release. Use RandStream.setGlobalStream instead. > In qsubget at 152 In qsubcellfun at 322 In qsubcellfun at 246 See also qsub/private/fexec around line 90. TODO inventorize the random number generator initialization for all different matlab versions

I have fixed it for matlab2012a, there are now three sections for different versions. roboos@mentat001> svn commit Sending qsub/private/fexec.m Transmitting file data . Committed revision 6351.

I have tested the following n = 20; qsubcellfun(@rand, repmat({10},1,n), 'timreq', 600, 'memreq', 100e6) on MATLAB version 2009b (7.9) up to and including 2012a and did not get any errors w.r.t. random numbers. On version 2009a (7.8) there was an unrelated problem, see bug # 1648. I did not test any versions prior to 2009.
