matlabpool open local (inside a loop)

Hey! I am making this script where I need to have matlabpool open local inside a loop because I would be executing the same code on different amounts of workers. The problem is that when I start my loop at i=1, and then put matlabpool open local i, matlab does not want to take i as the number of workers I want, I only can take a number instead of a variable. Is there any way of having matlabpool open local inside a loop and changing the amount of workers each time? Thanks!

matlabpool('open','local',i)
but are you sure that you want to allocate 1 worker to the first iteration, 2 workers to the second iteration, and so on ?

feature('jit','off'); feature('accel','off')
should do that. However, that isn't usually the best way to proceed as it will give distorted views of what MATLAB is able to do.
What you should do instead is run the code first, with any convenient number of workers (e.g., 1), and throw away that timing result, and then go through your loop.
