I have a row vector and two column vectors, and intend to perform their multiplication (element by element). The following is an example.
t = [1 2];
s = [(1:3)',(4:6)'];
The expected result:
1 4 2 8
2 5 4 10
3 6 6 12

One way:
t = [1 2];
s = [(1:3)',(4:6)'];
reshape(t.*s(:),size(s,1),[])
ans = 3×4
1 4 2 8 2 5 4 10 3 6 6 12
