10折交叉验证代码 自编函数 可用于任何数据 直接使用即可(10 fold cross validation code editing the function can be used in any data can be used directly )

Function to generate a voice signal, adding noise, and filtering to recover the original signal.

一个简单的m序列产生函数，通过调用primpoly获得本原多项式，然后通过移位循环寄存器产生所需要的序列。自相关图形上能看到峰值旁瓣电平(PSL)和积累旁瓣电平(ISL)。(A simple code for generate m-series pseudo-random sequence based PRIMPOLY function which we get the prime polynomials first,then we get the feedback connect coefficient of the cycle shift registers which generate m-series sequency. the PSL and ISL of autocorrelate function is computed on the figure. )

主要是计算LD中光场的分布，以及在稳态条件下载流子的增益，属于稳态条件下简单的情况(Mainly calculated in LD light field distribution, and the steady-state condition downloading carriers gain, belonging to steady state conditions the simplest case)
