Hi,

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.

Thanks.

Jianjun
