I have 2 vectors and i want to obtain a correlation between them like y=ax+b by using regression, but i don't know how to use this code. would anyone help me with this?

coeffs = polyfit(FirstVector, SecondVector, 1);
Then coeffs(1) will be your a, and coeffs(2) will be your b.

Note that when I say "a different way of writing the same thing", I mean that polyfit() really does construct those matrices and use the \ operator.
