Publisher review:Fast Chebyshev Transform transforms between nodal and spectral values. This script allows for fast transformation between nodal and spectral values at the Chebyshev-Gauss-Lobatto points by using the built-in functions fft/ifft.
I've tested it with truncation as high as N=2^20 and it takes 1.7820 seconds. This script will handle an arbitrary number of data sets of the same length simultaneously. Requirements: ยท MATLAB Release: R14
Fast Chebyshev Transform is a Matlab script for Mathematics scripts design by Greg von Winckel.
