I have two arrays, and I was wondering how to take one array term by term and multiply it to all elements of another ray. For example:
A = [4 ; 5 ; 2]
B = [7 ; 8 ; 9]
I want to take each individual term of A and multiply them to B to get three separate arrays:
AB4 = [28; 32; 36]
AB5 = [35; 40; 45]
AB1 = [14; 16; 18]
I know I can do this manually (by using A(1) for example), but I will need to this for massive arrays. In fact, one of the arrays for A is of the size and type:
<150902x1 uint8>
Therefore typing it manually is out of the question. Any idea on how to do this?
Any help at all would be appreciated. Thank you in advance!

result = bsxfun(@times, A, B')
