Your help has been really precious in order to understand the flow.
But i would be glad if you suggested me a way, if possible, to get just the
matrix that evaluate_models() creates. I want it just befor LU decompostion
takes place. Should i change the code in order to get what i want or there
is an easier way or something already implemented?
