%ISBANDED  Determine if  gpuArray matrix is within specific bandwidth.
%   
%   TF = ISBANDED(A,LOWER,UPPER) returns logical 1 (true) if matrix A is 
%   within the specified lower bandwidth, LOWER, and upper bandwidth, UPPER; 
%   otherwise, it returns logical 0 (false).
%   
%   Example:
%    
%      A = gpuArray([2 3 0 0 ; 1 -2 -3 0; 0 -1 2 3 ; 0 0 -1 2]);
%      isbanded(A,1,1) % = 1
%      isbanded(A,0,1) % = 0
