In The Mathematica Journal 4(1): 81, Andrew Watson gives code for the Discrete Cosine Transform. All code for this journal issue is available from MathSource at http://www.mathsource.com/cgi-bin/MathSource/Publications/Periodicals/TheMathematicaJournal/0207-391 Cheers, Paul ____________________________________________________________________ Paul Abbott Phone: +61-8-9380-2734 Department of Physics Fax: +61-8-9380-1014 The University of Western Australia Nedlands WA 6907 mailto:paul@physics.uwa.edu.au AUSTRALIA http://www.pd.uwa.edu.au/~paul God IS a weakly left-handed dice player ____________________________________________________________________
