Linear Regression - Fourier Series

I need to find the Fourier series coefficients of an arbitrary x,y data set over an arbitrary number of series terms using a general linear least squares technique.
the fourier series represents a function f(x) as
f(x)=a_0/2 + sum(a_n*cos(n*x) + b_n*sin(n*x))
any help would be great!

Is this a homework problem where your answer has to be in a certain prescribed formulation, or are you trying to do an actual fitting problem?
