function s=wvltsize(lx,k)

% WVLTSIZE  Calculates the final size of a Wavelet transform.
%
%           WVLTSIZE (LX,K) returns the size of the K-scales 
%           wavelet transform of a vector of length LX. 
%           The length of the wavelet transform may be grater
%           than the original signal because of the method
%           used to transform odd length signals.

%           See also: MAXRSIZE, WT, IWT, WT2D, IWT2D.
