mprefilter

A multiwavelet prefilter turns a univariate sequence into a bivariate
(in this case) sequence suitable for processing by a multiwavelet
transform, such as <code>mwd</code>. As such, the prefilter is used
on the forward transform.
Not intended for direct user use.

wavelet packet transforms, multiple wavelet transforms,
