Parallel Code

Hi
Can I run this code in parallel?
A1=F(A1,B1)
A2=F(A2,B2)
F is a function, A1 B1 are unrelated to A2 B2
How can I do this ? ( now it runs one after the other)
Thanks
Shani

If you have Parallel Computing Toolbox, you could do this:
% first start up 2 local workers
matlabpool open local 2
% Make cell arrays of inputs
Ain = {A1, A2}; Bin = {B1, B2};
parfor ii=1:2
% Return outputs as a cell array
Aout{ii} = F(Ain{ii}, Bin{ii});
end

You should not open and close the pool each time - you should open the pool once and leave it open. Each time the pool opens, you are creating new workers with a fresh random number generator state.
