Gradient3D

DESCRIPTION

This module calculates the gradient of a three dimensional uniform scalar field. A centered difference algorithm is used to create the 3 component vector field: grad(f(i,j,k)) = ((f(i+1,j ,k )-f(i-1,j ,k ))/delx, (f(i ,j+1,k )-f(i ,j-1,k ))/dely, (f(i ,j ,k+1)-f(i ,j ,k-1))/delz)
