How do I multiply vector elements in the following fashion???

Suppose I have A=[18 44 20 55] & B=[4 6]
Now I want C=[18*4 44*4 20*6 55*6]
i.e I want to multiply first element of B with first pair of elements in A
and second element of B with second pair of A and so on...

A=[18 44 20 55]
B=[4 6]
out=reshape(bsxfun(@times,A',B),1,[])

Actually I want answer to be Out=[18*4 44*4 20*6 55*6] i.e total
number of elements should be same as in A i.e 4 in this case
Then you have to reshape A
reshape(bsxfun(@times,reshape(A,2,2),B),1,[])
Thank you
