Hi. Sorry for the delay. I've finally managed to put the solving function to work, it was my error on the elements' calculations...
It's actually a HUGE matrix, about 2679x2679, it takes me around 1 min to solve, while in fortran it took only 2 or 3 secs. I know it can't actually be direcly compared, but it's like 20 or 30 times slower :\ Is there any chance to make this faster?
Thanks A LOT, again :)
