matlab - How to shift zero in the last column of a matrix

Question

I have one matrix like below-

A=[1 1 1 1 1;
   0 1 1 1 2;
   0 0 1 1 3]

But I want to place all the 0 at the end of the row, so A should be like-

A=[1 1 1 1 1;
   1 1 1 2 0;
   1 1 3 0 0] 

How can I do this? Matlab experts please help me.

Answer 1

A more generic example:

A = [1 3 0 1 1;
     0 1 1 1 2;
     0 0 1 1 3]

% Sort columns directly
[~,srtcol] = sort(A == 0,2);
% Sorted positions 
sz  = size(A);
pos = bsxfun(@plus, (srtcol-1)*sz(1), (1:sz(1))'); % or use sub2ind

The result

B = A(pos)
B =
     1     3     1     1     0
     1     1     1     2     0
     1     1     3     0     0
