Dot Product of row vectors using loops not functions

I'm struggling to code the function of a dot product using only loops. Vector a1= [1 1 1] and a2=[2 2 2] and I understand the dot product is 6, but my resultant vector is [2 2 2] when I need it to be 6. Any thoughts?

Without any MATLAB functions:
result = 0;
for i=1:col1
result = result + a1(i)*a2(i);
end

result = dot(a1,a2)
Why do you need a for loop ?
