说明：  利用粒子群算法求最小值，对基本粒子群做了修改，使其有更好的计算效果。(Using Particle Swarm Optimization for the minimum of basic particle swarm made changes to make it a better calculation of results.)

对广义高斯分布有个基本的认识，为以后的应用打下基础(The generalized Gaussian distribution have a basic understanding of lay the foundation for future applications)

说明：  基波和三次谐波检测的Matlab径向基神经网络程序，自己写的(The Matlab radial basis neural network program for fundamental and third harmonic detection, written by myself)

这是在matlab下可以运行的dv-hop程序，程序经本人测试，可以正确运行(This is in the running of the matlab dv-hop program, the program I test, can correct operation)

分数阶傅里叶变换（FrFT）的程序，采用Ozaktas的第二种离散化方法。(Fractional Fourier transform (FrFT) program, using the second method Ozaktas of discrete.)

HL计算工程结构可靠度的简单算例2 包含1.例题文件，2.HL法计算，3.Matab自带抽样，4.自编monte carlo抽样(HL Method and Monte Carlo Method for Solving Reliability Index of Structures)

单纯形法matlab程序 求解标准型线性规划:max c*x s.t. A*x=b x>=0 本函数中的A是单纯初始表，包括:最后一行是初始的检验数，最后一列是资源向量b N是初始的基变量的下标 输出变量sol是最优解, 其中松弛变量（或剩余变量）可能不为0 输出变量val是最优目标值，kk是迭代次数( example：max 2*x1+3*x2 s.t. x1+2*x2<=8 4*x1<=16 4*x2<=12 x1,x2>=0)

函数通过输入信号序列和函数序号，以及调制解调选择参数来完成扩频调制解调。original_seq是原始输入序列，可能是未调制序列，也可能是调制序列，walsh_num是walsh函数的序号，select选择对输入的序列进行调制还是解调。(function through the input signal sequence and function of the serial number and choice of modulation and demodulation parameters to complete spread spectrum modulation and demodulation. Original_seq is the original input sequence may not be modulated sequence, and may also be modulated sequence, walsh_num walsh function of the serial number, select choice of input sequence modulation or demodulation.)
