可进行短时平均能量，短时平均幅度，短时平均过零率，短时自相光，短时傅里叶变换的函数,使用方便，(The average energy can be short-term, short-term average rate, the average short-term zero-crossing rate, short-term autocorrelation of light, short-time Fourier transform of the function, easy to use,)

通过matlab实现基于奇异值分解的转子故障诊断(Through matlab SVD-based Fault Diagnosis of Rotor)

这是一个kernel lpp流行学习算法（Kernel Locality Preserving Projections），(Kernel Locality Preserving Projections for manifold usingmatlab)

牛顿迭代法来解决线性方程等相关问题，用于数值分析考试的源代码程序。(Newton method to solve linear equations and other related issues, for the numerical analysis of the source code for examination procedures.)

采用累计贡献率的方法，BP神经网络的整个训练过程,有信道编码，调制，信道估计等。( The method of cumulative contribution rate The entire training process BP neural network, Channel coding, modulation, channel estimation.)

说明：  BP神经网络的仿真，能够拟合各种函数，支持梯度下降法和LM两种训练算法。所有代码自己编写，没有使用matlab自带的函数，是学习的最佳范本。(The simulation of BP neural network can fit various functions and supports two training algorithms, gradient descent method and LM. All the code is written by myself, without using the functions that come with matlab, it is the best model for learning.)

基于simulink的（2，1，2）卷积码在二进制对称信道中的系统仿真(Based on simulink the (2,1,2) convolutional codes in the binary symmetric channel of the system simulation)
