Trig Function Grapher

Functions NELSONFUN and NELSONFIT evaluate and fit (with non-linear least-squares) the Nelson-Siegel function, a popular yield-curve approximation device.

ELLIPTIC12i evaluates the Incomplete Elliptic Integrals of the First, Second Kind and Jacobi's Zeta Function for the complex value of phase U. Parameter M must be in the range 0

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.
