ORTHPOLYFIT, ORTHPOLYVAL

This toolbox supports the direct transform of a multivariate series by the fourier series expansion for a given set of polynomials using Gaussian quadrature methods. Any classical set of polynomials is implemented and could be easily used, i.e. shifted and unshifted Chebyshev, generalized Laguerre, shifted and unshifted Legendre, unmodified and modified Hermite, Gegenbauer, shifted and unshifted Jacobi. The Inverse transform is supported as well.For more information please read the related Contents.m file.
