compute the sum of each item of a vector with every item of another vector

Dear matlab community,

i came across a simple problem, which should be easily solved by one of the more experienced members.

I have two vectors, say

1

2

3

and

4

5

6

Now, I want to compute sums with each of the vector item from the first vector and every vector item of the second vector, that the answer is as follows:

1+4

1+5

1+6

2+4

2+5

2+6

3+4

3+5

3+6

Thank you very much!
