在Juan Cardelino发布的FMM(fast marching methos)2维程序基础上改写的3维程序。并改写成适合复杂速度模型，可用于地震旅行时计算。大模型3d算法在matlab下计算速度较慢，根据源码中的注释很容易改写成c程序。(3D FMM program revised from Juan Cardelino s 2D version. The program can calculate the seismic traveltimes in 3D complex model)

一个关于数字图像处理中角点提取的程序，使用harris算法，效果还不错。(On digital image processing in the corner extraction process, the use of harris algorithm, the effect was not bad.)

使用matlab软件编程，进行字母识别处理(using Matlab software programming, in alphabetical identification processing)

混沌系统的李亚普洛夫指数的求解，步骤很详细，可以适用于不同的混沌系统。(Chaotic system Lyapulov Index solving steps in detail, can be applied to different chaotic systems.)

利用扩展卡尔曼滤波器对已知环境地图进行估计，得出估计位置，并给出了真实轨迹(Using extended Kalman filter to estimate the known environment map, draw the estimated location, and provides true trajectory )

LMS Equalizer. implement equlizer with special channel rsponse

ICA watermarking. Blind, fragile, robust

说明：  用matlab写的维纳滤波，最陡下降法的实现例程。(Matlab written by Wiener filtering, the steepest descent method to achieve routine.)

说明：  matlab数字滤波器设计,计算出参数便于dsp实现bandpa(Matlab digital filter design parameters calculated to achieve bandpass ease dsp)
