function [AF,BF]=uwfbtbounds(wt,varargin)
%UWFBTBOUNDS Frame bounds of Undecimated WFBT
% Usage: fcond=uwfbtbounds(wt,L);
% [A,B]=uwfbtbounds(wt,L);
% [...]=uwfbtbounds(wt);
%
% UWFBTBOUNDS(wt,L) calculates the ratio B/A of the frame bounds
% of the undecimated filterbank specified by wt for a system of length
% L. The ratio is a measure of the stability of the system.
%
% UWFBTBOUNDS({w,J,'dwt'},L) calculates the ratio B/A of the frame
% bounds of the undecimated DWT (|UFWT|) filterbank specified by w and
% J for a system of length L.
%
% UWFBTBOUNDS(wt) does the same thing, but L is the length of the
% longest filter in the identical filterbank.
%
% [A,B]=UWFBTBOUNDS(...) returns the lower and upper frame bounds
% explicitly.
%
% See WFBT for explanation of parameter wt and FWT for explanation
% of parameters w and J.
%
% The function supports the following flags:
%
% 'sqrt'(default),'noscale','scale'
% The filters in the filterbank tree are scaled to reflect the
% behavior of UWFBT and IUWFBT with the same flags.
