Chebfun

Description:Global root solver, minimum and maximum via Chebyshev expansions. Uses a custom parser in C, and recursively solves for all roots via eigenvalue solving of the (implicit) companion matrix. Uses a fast experimental solver. Has some utilities for Chebyshev transformation, fast parser, plotter and various FFT transformations and CDT included in the library. Parses and solves a Chebyshev expansion of size 129 in about 1 second. Can handle Chebyshev expansions up to 1025. Does not work on a regular calculator; requires a custom HPGCC ROM on a 50g to run.
