Adding a frame of zeros to a matrix

I have a matrix 19x9 I want to add a frame of zeros so I will be 20x10 ?????

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');

Actually I want to add the zeros as frame for all corners So the original matrix would be surrendered by zeros like square

[Guillaume]

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]);
