Not sure which corner you want to pad with zeros. I'm assuming bottom right:
newmatrix = [yourmatrix, zeros(size(yourmatrix, 1), 1); zeros(1, size(yourmatrix, 2) + 1)];
If you have the image processing toolbox:
newmatrix = padarray(yourmatrix, [1 1], 'direction', 'post');

newmatrix = [zeros(1, size(yourmatrix, 2) + 2); zeros(size(yourmatrix, 1), 1), yourmatrix, zeros(size(yourmatrix, 1), 1); zeros(1, size(yourmatrix, 2) + 2)];
Using padarray:
newmatrix = padarray(yourmatrix, [1 1]);
