%BANDWIDTH returns the lower and upper bandwidth of a matrix.
%   [LOWER,UPPER] = BANDWIDTH(X) returns the lower bandwidth LOWER, and the upper 
%   bandwidth UPPER of matrix X.
%   
%   LOWER = BANDWIDTH(X,'lower') returns the lower bandwidth LOWER of matrix X.
% 
%   UPPER = BANDWIDTH(X,'upper') returns the upper bandwidth UPPER of matrix X.
