Multiplying Matrices, but with elements added together

Hello!

I have vector matrix A (3x1) and row matrix B (1x3). When multipying A*B, instead of having each element in the new 3x3 matrix be the elements multiplied together, is there a way to still make the 3x3 matrix but instead of each element of one matrix being multiplied by the elements of the other matrix, they would be added together.

If I don't make sence please tell me, I am new to MATLAB. Image of desired outcome below.

Thanks!

Yes, there is!

Try this:

A = [2; 3; 4];
B = [1 3 5];

C = bsxfun(@times, A, B)                        % Before R2016b
C = A * B                                       % R2016b And Later

producing (for both):

C =
     2     6    10
     3     9    15
     4    12    20

Sorry for the trouble, but I posted the wrong picture originally, there is a new one.

No worries!

The code for ‘C’ changes slightly:

C = bsxfun(@plus, A, B)                         % Before R2016b
C = A + B                                       % R2016b And Later

producing:

C =
     3     5     7
     4     6     8
     5     7     9
