MATLAB环境下信号的聚集或短时累积功率谱计算（MATLAB R2018A）

The present code is a pair of Matlab functions that provide a computation of the cumulative (integrated) power spectrum of a signal. Two functions are developed – one for the aggregated cumulative power spectrum computation and one for the short-time cumulative power spectrum.

The cumulative spectrum is an alternative (and often insightful) way of presenting the information given by the traditional spectral analysis. At each frequency, the cumulative line spectrum gives the percent power accumulated up to that particular frequency. By definition, the y-axis on the cumulative spectrum plot starts at 0% and ends at 100%.
