Curl Of A Vector Field

Program given here computes the discrete transfer function of a DC motor (Example taken in this case) using pseudo inverse technique. The input and output data for any single input single output system can be used to find out the discrete transfer function of that system.

This function uses the Vincenty direct algorithm to solve the "forward geodesic problem," which is the problem of computing the endpoint of a geodesic (shortest-distance) path on the ellipsoidal earth, given the start point, a path length, and a starting azimuth. This process is also called...
