WebAug 18, 2004 · Well, one thing you can do is assume only N coefficients count, e.g. f (t) = sum_ {k=a}^b c_k exp (ikt) where a=- (N-1)/2,b= (N-1)/2 if N is odd, or perhaps a=-N/2+1,b=N/2 if N is even, and solve the N x N system of equations y_j = sum_ {k=a}^b exp (ik t_j) c_k But this is really equivalent to a Lagrange interpolation problem: y_j exp (-ia t_j ...
