FNWT_PO

Nonstandard Wavelet Transform (Periodized, Orthogonal)

Calling Sequence

nwc = FNWT_PO(x,L,qmf)

Parameters

Inputs:

x :

1-d signal. length(x) = 2^J.

L :

coarsest resolution level

qmf :

quadrature mirror filter

Outputs:

nwc :

nonstandard wavelet transform of x contains both low-pass and high-pass outputs of pyramid algorithm. length(nw) = 2*length(x)

Description

if x is a vector and M is a matrix, then one can calculate Mx in two ways: (a) Use natural basis: M*x (b) Use nonstandard matrix product: INWT[NSF * FNWT[x]] where NWT and INWT are nonstandard wavelet transforms and NSF is the nonstandard form of the matrix.
