Daily Download 21: Assorted Solvers

Today’s download starts with some simple linear interpolation methods used to solve polynomial equations, leading on to more sophisticated methods using quadratic or inverse quadratic interpolation. Also included is a solver for differential equations using the Cash-Karp Method, which is a refinement of the Runge-Kutta Method.

The current download files are:

Newton’s method:
Quadratic and Inverse Quadratic interpolation:
Brent’s Method
Ordinary differential equation solver (Cash-Karp Method)
