mpostfilter

A multiwavelet postfilter turns a multivariate sequence into a univariate
sequence. As such, the postfilter is used
on the inverse transform, it is the inverse of an earlier used prefilter.
Not intended for direct user use.

math

Performs 1, 2 and 3D real and complex-valued wavelet transforms,
nondecimated transforms, wavelet packet transforms, nondecimated
wavelet packet transforms, multiple wavelet transforms,
complex-valued wavelet transforms, wavelet shrinkage for
various kinds of data, locally stationary wavelet time series,
nonstationary multiscale transfer function modeling, density
estimation.
