代码说明:

  相关函数法该方法先由序列估计出自相关函数R,然后对其进行傅立叶变换,得到功率谱估计。当延时和数据长度相比很小的时候可以有良好的估计精度。 (Correlation function method that the method is estimated by the sequence from a correlation function R, then its Fourier transform, the power spectrum estimation. When the length of delay and data can be compared to a very early age have a good estimation accuracy.)

    T_XTIDE Tidal prediction YOUT=T_XTIDE(STATION) makes a tidal prediction for the current day using the harmonics file XTIDE. Predictions at other times can be generated using [...]=T_XTIDE(STATION,TIM) where TIM is a vector of matlab-format decimal days ( DATENUM). If TIM is a scalar then it is taken as the number of days present over which to make predictions. If TIM>1000 then it is taken to be the starting time in matlab-format. at the matlab time JD (UTC, but see code for details) where tau = lunar time s = mean longitude of the moon h = mean longitude of the sun p = mean longitude of the lunar perigee np = negative of the longitude of the mean ascending node pp = mean longitude of the perihelion (solar perigee)
