中文说明： Relief计算分类权重，ML法能够很好的估计信号的信噪比,音频信号通过LM386放大，计算多重分形非趋势波动分析matlab程序,迭代自组织数据分析，这个有中文注释，看得明白。
English Description：
Relief classification weight is calculated and ML methods can be a good estimation of the signal to noise ratio, audio signals through the LM386 amplifier, non-trend volatility calculated multifractal analysis MATLAB program, iterative self organizing data analysis, the Chinese comments, understand it.
