UviWave is a freeware Wavelet Matlab toolbox developed at the University of Vigo, Spain. The package web page is http://www.tsc.uvigo.es/~wavelets/uvi_wave.html.
Unfortunately, their server is quite difficult to connect to. I have written to the UviWave people to tell them about the situation. For the moment, I have decided to make the Uviwave package available for downloading on my server. The archive is avalable in two formats:
Uvi_Wave.300.sit (binary stuffit archive, 307 K) and Uvi_Wave_300.zip (312 K)
