I have a multi core system and in order to do performance profiling I
would like to restrict Matlab to use no more than one of the available
cores. Is there a way to do this at the OS level? Matlab can restrict
itself to a single thread but this isn't the same. Other OS's refer to
this capability as the "Processor Affinity".

Thanks,
Curt
