Non-linear equations system solver (Newton Raphson)

This code solves a system of non-linear equations.
It is practical to use since there's no need to enter the derivation matrix (the code calculates itself).
Also, there's an indetermined number of variables (no restriction). You can put 1 million equations! :)
Inside the code there are instructions of how to use it, and also a folder with a simple exemple.
Hope it's going to be usefull for you! Comments and debugs are deeply enjoyed.
