Partial derivative of a matrix

I have a matrix V, say 3-by-3. How can I compute dV/dx and dV/dy separately? dV/dx is partial derivative wrt x (along the columns), same for y. I use gradient function, but it returns a matrix of same size as V. Any help or idea? Thanks.

[Vx,Vy,Vz] = gradient(V,h);
[Vx,Vy,Vz] = gradient(V,h1,h2,h3);
If your domain is more complicated or you are looking for higher order operator lookup Finite Difference schemes or Finite Volume ones.
