  I am confused by the function of ezfftf. The output is supposed to be
the coefficients of the harmonics. For example, cf(0,i) and cf(1,i) are
the coefficients of some sin and cos harmonic components. How to express
the wave length or the frequency of that harmonics in terms of "i" and the
interval and number of the periodic time series? Assume the time series
data has interval of T, and the total number is n.
