Description: The inverse of the gradient function. I ve provided versions that work on 1-d vectors, or 2-d or 3-d arrays. In the 1-d case I offer 5 different methods, from cumtrapz, and an integrated cubic spline, plus several finite difference methods.
In higher dimensions, only a finite difference/linear algebra solution is provided, but it is fully vectorized and fully sparse in its approach. In 2-d and 3-d, if the gradients are inconsistent, then a least squares solution is generated Platform: |

This MATLAB M-file implements the finite-difference time-domain
solution of Maxwell s curl equations over a three-dimensional
Cartesian space lattice comprised of uniform cubic grid cells.
Each unit cell within the Yee lattice contains electric field
components sampled along the edges of the cube and magnetic field
components normal to the faces of the cube (the dual of Fig. 3.1).
