hello,
I would like some advice on this: I have an image characterized by a rectangular mesh and I would like to convert it to a square mesh by resampling.
Thanks for your suggestions

That's awfully vague. An example of the expected inputs and outputs would help. Otherwise, all I can suggest is imresize().
% a "rectangular mesh"
sz = [101 301];
A = zeros(sz);
A(:,1:20:sz(2)) = 1;
A(1:10:sz(1),:) = 1;
% show it
% the cells are rectangular, so is the image.
imshow(A)
% resize it
B = imresize(A,sz.*[2 1],'nearest');
% show it
% the cells are square, but the image is rectangular
imshow(B)
% resize it
C = imresize(A,sz(2).*[1 1],'nearest');
% show it
% the image is square, but the cells are rectangular
imshow(C)
