%UWPFBTBOUNDS Frame bounds of Undecimated WPFBT
%   Usage: fcond=uwpfbtbounds(wt,L);
%          [A,B]=uwpfbtbounds(wt,L);
%
%   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.  
%
