%BANDWIDTH  Return the lower and upper bandwidth of a gpuArray matrix.
%   
%   [LOWER,UPPER] = bandwidth(X)
%   LOWER = bandwidth(X,'lower')
%   UPPER = bandwidth(X,'upper')
%   
%   Example:
%    
%      A = gpuArray([2 3 0 0 ; 1 -2 -3 0; 0 -1 2 3 ; 0 0 -1 2]);
%      [lower, upper] = bandwidth(A,1,1) % = 1, 1
