% Continuous:Contents  v802 -- Continuous Wavelet Transform tools
%
% The routines in this directory perform periodic Continuous Wavelet
% Transforms of 1-d signals, and tasks associated with CWT -- ridge and
% skeleton extraction. The underlying computations are completely
% different than in the usual orthogonal wavelet transforms -- they are
% all based on convolution with gaussian-type windows, using frequency
% domain implementations. Reconstruction is of little interest. Instead,
% the aim is to calculate local scaling exponents at various points in
% the signal, and to calculate generalized fractal dimensions.
%
% Attention; if signal length n=4096 and you use 12 voices per octave, you
% will need maybe 32 MB of RAM to successfully run this sequence of tools
% without an OUT-OF-MEMORY problem
