Re: Easy Wavelet capability added to Octave core software

[PattiMichelle]

Thanks very much for your help, Mark, and for moving my thread to the correct list!  (I am attaching your modified wavepath.m file for archival purposes)  My problems also stem from being a newbie to Octave - it's been 20 years since I used MatLab so I forget the syntax entirely, but it's starting to dimly come back from seeing your code.  I was able to get WaveLab installed but haven't been able to test demos yet.  I have both versions of Octave installed with jhandles and GNUplot backends and will test them.

Patti
