Hi ! need help to match the size of two matrices. I have two matrices of dimensions mxn and jxk. I want make mxn of size jxk by adding zeros at the end of the mxn. A of mxn dimenssion and B of jxk dimenssion. Am doing by this way:
newA=[A,zeros(size(B)]

newA = [A, zeros(size(A, 1), size(B, 2)-size(A, 2)); zeros(size(B, 1)-size(A, 1), size(B, 2))];
Assuming that both dimensions of B are greater than A.

Another way:
newA = zeros(size(B));
newA(1:size(A,1),1:size(A,2)) = A;
