The solution in @Dyuman Joshi's comment above assumes that a and b are row vectors. If they are column vectors, it will result in matrix output.
Better to use dot(), I would say. See my solution.

Ran in:
Assuming you actually have vectors, and not variables named a0, a1, a2, etc., then you can use the dot function:
a = [1 2 3]';
b = [4 5 6];
dot(a,b)
ans = 32
Note that this will work on row vectors, column vectors, or even a mixture (which is how I defined them in this example).
