Solving Optimal Control Problems using Chebfun
WebChebfun is an open-source software system for numerical computing with functions. The mathematical basis of Chebfun is piecewise polynomial interpolation implemented with what we call “Chebyshev technology”. The foundations are described, with Chebfun examples, in the book _Approximation Theory and Approximation Practice_. WebThe trigcoeffs function can also be used in combination with the Chebfun constructor to generate truncated Fourier series representations of functions. Here's an example for the above square wave using 15 Fourier modes: numModes = 15; c = trigcoeffs … Chebfun is compatible with MATLAB 7.9 (R2009b) or later, and is freely available … Chebfun Examples illustrate everything from rootfinding to optimization to … What is Chebfun?
