Does anyone have an idea whether its advantageous to use a parforloop on a single quadcore? I have some code that calculates in each iteration a set of integrals (a few with infinite boundaries) which can take up some time. However, matlab uses already functions that are multithreaded on their own. I tested it quickly, but it was slower dan ever (probably I still have to adapt my code a little bit to optimize it). However, I'd like to have an idea whether I should put some work in it or not. To give you an idea of the computation time, some integrals take more than one minute to calculate.
