语音信号处理，画20分拿到的。看看吧，有帮助的。(Signal processing, painting got 20 points. Look, there is help.)

说明：  用于画出lorenz的利亚普诺夫指数，该文件算法优秀，比同类程序运算速度快很多(Draw for the Australian Punuo Fu Index lorenz)

用于本科生电力系统稳态分析的潮流计算，本模板以三机九节点为例为例(It can be used as a template of powerflow.（steady-state analysis of power system）)

这是三组程序，分别计算hibert变换，小波时频分布，wigner-vill分布，并且画出谱图(This is three groups of program, calculate hibert transform, wavelet time-frequency distribution, wigner- vill distribution, and draw the spectrogram)
