***	WAVELET TRANSFORMS AND THRESHOLDING IN 1 AND 2 DIMENSIONS FOR S   ***
			Version 2.1

WHAT:	S software to compute the 1- and 2-dimensional wavelet transform
	using Mallat's pyramidal algorithm with Daubechies compactly supported
	orthonormal wavelets and incorporating an implementation of the
	thresholding ideas of Donoho and Johnstone.

	Package consists of:

		* S functions that compute the 1- and 2-dimensional
		  discrete wavelet transform, and inverse. (Uses
		  dynamically loaded C code)

		* S functions to perform thresholding

		* S functions to plot and interpret sets of wavelet coefficients

		* Full on-line S help

WHERE:	Obtain via anonymous FTP from

		gdr.bath.ac.uk

	Userid "anonymous" and your email address as the password.
	Software is in directory /pub/masgpn as the file "wavelet.shar.Z"
	Unpacking instructions in "README.Z". The transfer should be
	done using the BINARY transfer mode of ftp and then the files
	should be uncompressed using the UNIX command "uncompress".

	Extra draft documentation is in "dws.ps.Z" - a compressed PostScript
	file.

	ALSO available from the statlib archive (ftp: lib.stat.cmu.edu)
	userid "statlib", your email address as password. The software
	is in the "S" directory as "wavethresh".
