Use whole cpu for my n^2*2^n code

Hello,

When matlab executes my n^2*2^n code it uses only the one core of my cpu (only 25%). I tried pmode start local 4 and run my code but it runs 4 independent times at the same time. How can I use the whole cpu for one execution?

Thank you!!

Short of modifying the source code, you can't.

PMODE executes the same line of code on each worker - you need to make that line of behave differently on each worker by using distributed arrays, or code that depends on LABINDEX.

You might find it simpler to instead open a parallel pool of workers (known as MATLABPOOL in versions older than R2013b), and then use PARFOR.
