A question about product operation

Hello all!
I'm not sure if this was explained before, but I could not find any answer to this.
So, if i have x=[a b c] and y=[d e f] I'd like to know (if it's possible) how I could obtain:
.
z=
h i j
k l m
n o p
where:
h=a*d k=a*e n=a*f
i=b*d l=b*e o=b*f
j=c*d m=c*e p=c*f
Thanks!

x = [1, 2, 3]
y = [10, 20, 30]
z = x' * y
The matrix multiplication of a column vector with a row vector replies the dyadic product. x*y' would reply the dot-product.
Slower alternative:
z = bsxfun(@times, x', y)

I also tried to use the blocks from the "User-defined functions" but I did not succeed.
Please show us, what you have tried and explain "did not succeed" with details.
