求时间序列的功率谱，包括周期图法和自相关函数法(Find the power spectrum of the time series, including periodogram and autocorrelation function method)

HHT MATLAB CODE HHT是一個客觀而有自適性(adaptive)的數據分析方法。它利用物理空間的尺度為基準分解複雜數據，因此各分量皆有豐富的物理意義。由於它有自適的特性，它可以適用於分析非線性，非穩定性過程所產生的數據。經過近數年來的廣泛研究與應用，HHT已被認定為是一個有革命性又有效的方法。(HHT MATLAB CODE)
