My problem is somewhat different... I have the partial derivatives with respect to a, b and c but would like partial derivatives with respect to x, y and z. I have used a stencil (I think) in order to get the partials with respect to a, b and c.

Homework Statement Hey I am trying to evaluate d/dx, d/dy and d/dz of a wavefunction defined on a grid. I have the wavefunction defined on equally spaced points along three axes a=x+y-z, b=x-y+z and c=-x+y+z. I can therefore construct the derivative matrices d/da, d/db and d/dc using finite...
