active shape model的matlab代码实现，用于图像处理，模式识别等方面(active shape model of matlab code for image processing, pattern recognition, etc.)

DBPSK调制模式在高斯信道下的误码率。(the ber performance of DBPSK through gaussian channel.)

A useful wrapper over the boost Mersenne Twister random number generator. It is implemented as a singleton such that the same instance can be used throughout a code by requesting the singleton instance. It also can return the host rng for boost functions that requires it. A unary function is also provided for use with std::random_shuffle for example.

用分步法 计算 耦合非线性薛定谔方程； 主要用于高功率锁模增益光纤激光器的数字模拟； 模拟步骤分四步：光纤损耗传输、色散、非线性、增益； finding 是主程序，其它是函数 (Digital-to-analog simulation steps coupled nonlinear Schrö dinger equation is mainly used for high-power mode-locked gain fiber laser with a fractional step in four steps: the fiber loss transmission dispersion nonlinear gain finding is the main program, other functions)

上硕士时用过的信号处理的Matlab代码，主要包括DFT、FFT变换滤波器设计、Matlab下的数字信号处理示例等内容，比较适合余初学者，谢谢。(When used on the master signal processing Matlab code, including DFT, FFT transform filter design, Matlab example under the digital signal processing, etc., more than suitable for beginners, thank you.)

说明：  使用单纯形算法整定pid参数的例程还可以(PID parameters tuning by simplex algorithm)
