@Carl Love 

Thank you so much!!!. Your suggestion helped me a lot. My main problem is to solve two equations with the numerical method Newton-Rapson. They are very complicated integral equations. The integrals are solved numerically. The process is tedious. I had hoped to parallelize the calculation of functions and their derivatives, but unfortunately the memory of my computer was not enough. Despite having 6 Gb of ram, the maple program used everything and stopped working.

Thanks alot.
