Adding zeros to a matrix to match the dimensions of two matrices.

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)]

I want size(newA)=size(B) but this way it becomes size(newA)>size(B). kindly urgent help needed.

Answer 1

[Guillaume]

 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.

Answer 2

Another way:

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

[Guillaume]

Yes, actually simpler than my answer. And in case A is not of class double:

newA = zeros(size(B), 'like', A);
