A = [1,5,6,3,2,1] B = [3,4,6]
I want to take each element in A and multiple it by all the elements in B. For example I want C = [3,4,6,15,20,30,18,24...]
I know this is really simple, I'm just missing it in the hlep.
Thanks much,
James

Kronecker tensor product:
kron(A,B)

Yet another possible solution
A = [1,5,6,3,2,1]
B = [3,4,6]
C=cell2mat(arrayfun(@(X)times(A(X),B),1:numel(A),'uni',0))
