A = [ 1 2 3 4];
B = [ 5 6 7 8];
C = reshape(bsxfun(@plus,A,B.'),1,[]);

Do you need to do this in MATLAB code ?
A = [ 1 2 3 4]
B = [ 5 6 7 8]
C = A + B = [ 6 8 10 12 ]
Comment back if your requirement is different.

A = 0:4;
B = 10:16;
bsxfun(@plus,A,B')

I found this conversation while looking for a faster way to accomplish this task. The code below also works but is just slightly slower in my code on my machine.
X=[A' ones(size(A'))];
Y=[ones(size(B)); B];
reshape(X*Y,1,[])
