How to use for loop structure to calculate two vectors to dot product

How to use for loop structure to calculate two vectors to dot product.

Please give an example.

Answer 1

[William]

a = 1:5;
b = 6:10;
c = 0;
for j = 1:5
    c = c + a(j)*b(j);
end

However, this calculation can be done more simply with the dot() function:

c = dot(a,b);

or with the expression:

c = sum(a.*b);

[Matt J]

or with matrix multiplication,

c=a*b.'
