用Chirp信号调制PN码 P采用上升频用下降频Chirp信号解调的方法(reproduce the PN code which was modulated by Chirp signal)

there is a matlab cod,that is, Example of Supercritical Hopf bifurcation.

该程序仿真了基于三相逆变器的空间矢量PWM。可以在示波器上看到线电压，相电压和滤波电压。调制指数、DC电压和频率参数可以修改。(The program simulates the vector PWM space-based three-phase inverter. You can see the line voltage, phase voltage and filtering the voltage on an oscilloscope. Modulation index, DC voltage and frequency parameters can be modified.)

perl programming for calculating the percentage of the average values.

This code is to implement hough transform. used in edge linking

余子式、行列式、逆矩阵、对数组进行全排列(Bulbil style, determinant, inverse matrix, wide array of arrays)

说明：  特征值的提取方式 有需要的可以下载试试 还不错(for the value )

该matlab程序主要进行肌电信号的预处理以及获取时域特征(The matlab program mainly for EMG signal preprocessing and access to time-domain characteristics)

一种改进的粒子群算法，进行多峰条件下的最值寻优，实测可行。(a improved PSO algorithm for tracking the best value)

说明：  测试实现时域LMS功能，需修改原始信号为模拟信号。(In order to realize LMS function in time domain, the original signal should be modified to analog signal.)
