After doing the finite difference approximation of a 2D heat equation. How do we put this equation into a matrix to solve it? I want the actual steps of putting the numbers in the rows of the matrix because i don't find anything that explains this :(( 1D equations are easy to implement but 2D equations seemed more tricky
