Hello,
I am trying to create a matrix by multiplication of two other but it is not a standard multiplication:
A=1x3 array
B=100x1 array
C = [A(1,1)*B, A(1,2)*B, A(1,3)*B];
Is there an easier way to create the C matrix? Thanks.

So what's wrong with that way? Looks fine to me.

Looks like pretty standard matrix multiplication to me, given the dimensions you've provided,
C=B*A;

You're in luck:
C = kron(A,B)
