Is there a way to parallelize independent instructions within a for loop? The loops themselves aren't independent, so parfor is not really an option.
What I would like to do is something like:
for ii=1:N
% initial stuff
[...]
% instructions 1
[...]
% instructions 2
[...]
% instructions 3
[...]
% instructions 4
[...]
% more stuff
[...]
end
The instructions1, instructions2 etc are all independent instructions, so they should be able to parallelize. Each loop in the for, however, is not independent, so is not just change the for to a parfor. Is there any way to do it in Matlab?

You could make scripts for each set of instructions and launch them (within the loop) on different workers using the batch command.
