UWPFBTBOUNDS - Frame bounds of Undecimated WPFBT

Usage

fcond=uwpfbtbounds(wt,L);
[A,B]=uwpfbtbounds(wt,L);

Description

uwpfbtbounds(wt,L) calculates the ratio \(B/A\) of the frame bounds of the undecimated wavelet packet filterbank specified by wt for a system of length L. The ratio is a measure of the stability of the system.

[A,B]=uwfbtbounds(wt,L) returns the lower and upper frame bounds explicitly.

See wfbt for explanation of parameter wt.

Additionally, the function accepts the following flags:

'intsqrt'`(default),'intnoscale', `'intscale'
The filters in the filterbank tree are scaled to reflect the behavior of uwpfbt and iuwpfbt with the same flags.
'sqrt'`(default),'noscale','scale'`
The filters in the filterbank tree are scaled to reflect the behavior of uwpfbt and iuwpfbt with the same flags.
