FWIIW I wrote a decent and general wavelet implementation in native J. Wrote about it in my blog though I didn't include all the pieces. https://scottlocklin.wordpress.com/2014/11/14/notation-as-a-tool-for-thought-wavelets-in-j/ My J verbs were pretty weak at the time; I think I was experimenting with the 13 : way of converting explicit to tacit, but maybe it helps. I coded it from looking at Mallat's book and the R waveslim package. Since I am lazy and never wrote the full wavelet package up and submitted it to pacman, I'll just push to github for whoever is interested. https://github.com/locklin/j-wavelet ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
