U2NONUCFMT - Uniform to non-uniform filterbank coefficient format

Usage

c=u2nonucfmt(cu,pk)

Input parameters

cu Uniform filterbank coefficients.

Output parameters

c Non-uniform filterbank coefficients.
p Numbers of copies of each filter.

Description

c = u2nonucfmt(cu,pk) changes the coefficient format from uniform filterbank coefficients cu (M=sum(p) channels) to non-uniform coefficients c (numel(p) channels) such that each channel of c consinst of p(m) interleaved channels of cu.

The output c is a cell-array in any case.
