HOW TO MOVE THE DIAGONAL ELEMENTS IN MATRIX (ONE PIXELS) FOR IMAGE PROCESSING

how to move the array

1 4 6 
8 2 3
7 9 5

all elements are move diagonally one pixel for m*n matix

I = [
     1     4     6
     8     2     3
     7     9     5]; % initial array

idx = reshape(1:numel(I),size(I));
for jj = -size(I,1) + 2 : size(I,2) - 2
    a = diag(idx,jj);
    I(a) = I(circshift(a,1));
end

Thanks a lot sir but i need that code for M*N matrix
