Why do I receive this error? Error using ==> psoptimset at 297 Unrecognized parameter name 'UseParallel'.

Why do I receive this error?

Error using ==> psoptimset at 297 Unrecognized parameter name 'UseParallel'.

when running this block of code

matlabpool open 2 
options = psoptimset('UseParallel', 'always', 'CompletePoll', 'on', 'Vectorized', 'off');

It seems I don't have a parameter 'UseParallel' in my psoptimset. I would like to turn this to always in order to run a Monte Carlo experiment over the function "patternsearch". I have MATLAB 7.5.0 2007b.

Thanks in advance

Hi,

this feature was introduced with 8a:

Parallel Computing Toolbox support was added to Global Optimization Toolbox starting in R2008a, as per the release notes here:

http://www.mathworks.com/help/toolbox/gads/rn/bre2ymp.html

so, if you're using R2007b, you will not be able to take advantage of that.

Thanks a lot!
