2D Chebyshev Transform

28 Jan 2004 (Updated 04 May 2004)

Transforms between 2d nodal and spectral data

File Information
Description	This is a very fast and efficient script for nodal-to/from-spectral transforms using chebyshev polynomials on the unit square domain. This version does not require 2^n truncation, but does require the same truncation in both dimension. Users are encouraged to improve and redistribute this script.
MATLAB release	MATLAB 6.0 (R12)

Updates
04 May 2004	This implementation is faster as it uses the built-in fft and ifft functions and is completely vectorized.
