need to solve a PDE ( basically a Poisson's equation with Neumann
boundary condition ), and I solved it using a steepest descent method,
which is very slow. Now I want to solve the PDE using GMRES. In addition, I do
have the matrix A, but I have a function which computes Ax, so I also need to
use the matrix free method.<o:p></o:p></span></p>
