As someone with severe Asperger's I can't understand programming and after 100s of hours trying to learn it just doesn't click.
I am looking for any suggestions on material to learn to solve an equation such as
Poisson equation on a square domain of 51 by 51
$$U_(xx_) + U_(yy_) = xy $$
$$(0,y)=0; (x, 0)=0; _(51,y)=; u_n(x, 51)=y$$
