function X = compute_subwindows_matrix(A,k,mask)

% compute_subwindows_matrix - compute a matrix containing each sub-windows.
%   
%   X = compute_subwindows_matrix(A,k,mask);
%
%   If A is of size [n,p], then X is of size [(2*k+1)^2,n*p].
%   Each row contains a sub-windows of A of size (2*k+1)x(2*k+1).
