MATLAB: How to calculate sum of all the possible combinations of two vector elements

Question

I have two vectors A and B with different lengths. The B vector always have 4 elements. How can I obtain the vector C containing sum of all the possible combinations of elements of B vector with A.

For example B= [1 2 3 4] and A= [0.1 0.2 0.3 0.4 0.5 0.6]

Then C= [1.1 1.2 1.3 1.4 1.5 1.6 2.1 2.2 2.3 2.4 2.5 2.6 3.1 3.2 3.3 3.4 3.5 3.6 4.1 4.2 4.3 4.4 4.5 4.6]

Thank you
