包络谱诊断轴承故障

说明：  calculator using matlab

连续信号（可以自定义的函数）的FFT效果图，初学者学习的例程，不错(Continuous signal (can custom functions) of the FFT renderings, for beginners to learn the routine, good)

说明：  总体最小二乘法的ESPRIT方法，这种算法的估计精度明显好于原来的ESPRIT算法。可以很好的估计出信号的角度。仿真中用的是均匀阵列。(Total least squares method of the ESPRIT method, the algorithm of the estimation accuracy significantly better than the original ESPRIT algorithm. Can be a very good signal to estimate the angle. Simulation using the uniform array.)

1．本程序演示的是用简单遗传算法随机一个种群，然后根据所给的交叉率，变异率，世代数计算最大适应度所在的代数 2．演示程序以用户和计算机的对话方式执行，即在计算机终端上显示“提示信息”之后，由用户在键盘上输入演示程序中规定的命令；相应的输入数据和运算结果显示在其后。 3．测试数据 输入初始变量后用y=100*(x1*x1-x2)*(x1*x2-x2)+(1-x1)*(1-x1)其中-2.048<=x1,x2<=2.048作适应度函数求最大适应度即为函数的最大值 (1. This program demonstrates a simple genetic algorithm is a random population, then according to the crossover rate and mutation rate, fitness for calculating the maximum number of generations in which algebra 2. Demo program to computer users and the implementation of dialogue, that is displayed on a computer terminal " message" after the keyboard input by the user specified in the order demo program the corresponding input data and results in a subsequent operation. 3. Test data input with the initial variables y = 100* (x1* x1-x2)* (x1* x2-x2)+ (1-x1)* (1-x1) where-2.048 < = x1, x2 < = 2.048 ask for the maximum fitness function is the function of the maximum fitness)

一些常用数值分析程序，希望对大家有所帮助。(some commonly used numerical analysis procedures, we hope to help.)

Dynamically create a variable. This should create a context extension.

matlab code for adaptive

butterworth高通滤波，里面有两个巴特沃斯高通滤波函数，我试过了，都可以用。(butterworth high-pass filtering, there are two high-pass Butterworth filter function, I tried, you can use.)

一种SSB调制与解调的MATLAB实现,其中用到了Hilbert变换(A method of SSB modulatie and demodulate using Matlab)
