PRTools4 A Matlab Toolbox for Pattern Recognition

这是一个电力系统信号，其中频率为200和300.应用付立叶变换并求频谱图 (This is a power system signal, including frequency of 200 and 300 apply Fourier transform and spectrum requirements)

ANSI input 5p1 implementation example

计算灰色关联度，参考因子与比较因子共同存储在一个矩阵，参考因子为第一列(failed to translate)

非线性信道matlab仿真程序，可以实现色散和非线性效应(nonlinear fiber)

说明：  求解tsp问题的遗传算法。可以直接求解TSP只要带入数据，修改特定的参数即可(Solving the problem of genetic algorithm tsp)

说明：  最简单的模拟退火算法，自己编的小程序，用于优化问题，求全局最小值。(simmulated annealing (SA))

可用于进行任意自由度的结构的动力时程分析，求解结构的动力响应，包含位移、速度以及加速度，然后对其进行傅里叶变换到频域，可通过滤波函数去除无关频率(The dynamic time history analysis of a structure with arbitrary degree of freedom can be used to solve the dynamic response of the structure, including the displacement, velocity and acceleration, then the Fourier transform to the frequency domain, and the unrelated frequency can be removed by the filter function.)

用Matlab实现的DES算法。在Matlab窗口输入DESDECP(a,b,n),其中a，b表示16进制的明文和密钥，n为1表示加密，否则表示加密。(DES algorithm using Matlab. In Matlab window field DESDECP (a, b, n), where a, b indicates a hexadecimal plaintext and key, n is 1 shows an encryption, or that encryption.)

matlab要求编写函数，并画出图的matlab习题，供大家参考(prepared Matlab functions, and draws a plan of Matlab Exercise, for your reference! !)
