matlab的时频分析源代码，针对小波分析和其他的时频方法，希望对大家有帮助！-time-frequency analysis matlab source code for wavelet analysis, and other time-frequency methods, we want to help!

基于matlab的hurst指数的估计方法，小波分析法，没有采用小波工具。-Matlab-based hurst index estimation methods, wavelet analysis。

It draws on principal component analysis algorithm (PCA), matlab wavelet analysis program, Time series data analysis Mellin transform tool.
