2D Chebyshev Transform
Updated Tue, 04 May 2004 09:44:23 +0000
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.
