Schalom!

After some further investigation I came to the not very pleasing conlusion that
the wtn of idl works with tensor waveletes with different scaling in the
two coordinate-directions. Bad! In that the question, how the wavelet-
coefficients are stored in the result-matrix of wtn is obsolet.

I'd like to have a decomposition in basis
functions:
m/2 m
PSI (x) = |det(R)| PSI(R x - k)
mk

with

R = 1 -1
1 1

m e Z

2
k e Z

Who has software for this type of 2D-wavelet-decomposition?

Thanks
Christian
