com.nr.fe.Chebyshev.polycofs()
Polynomial coefficients from a Chebyshev fit. Given a coefficient array c[0..n-1], this routine returns a coefficient array d[0..n-1] such that sum(k=0,n-1)dky^k = sum(k=0,n-1)Tk(y)-c0/2. The method is Clenshaw's recurrence (5.8.11), but now applied algebraically rather than arithmetically. @param m @return
