说明：  采用五点差分格式解决椭圆问题，这里是3个详例。(Using a five-point difference scheme to solve elliptic problems, here are three detailed examples.)

matlab lagrange程序，适合大家编辑matlab 的拉格朗日程序文件，分析。(matlab lagrange program，it is suitable for programmer use lagrange original program to solve relative problem。)

matlb编写的IIR滤波器程序，按照给定指标采用模拟低通滤波器（巴特沃思低通或者切比雪夫低通）去逼近理想模拟低通滤波器 ，然后通过双线性变换法对模拟滤波器进行数字化，得到数字滤波器 。(IIR filter matlb prepared by the procedure, according to set targets and analog low-pass filter (Butterworth low-pass or low-pass Chebyshev) approximation to the ideal analog low-pass filter, and then through the bilinear transformation method for analog filtering device to digitize, the digital filter.)

说明：  MATLAB程序（附图像），利用彩色AGV对路径进行识别。(MATLAB (AP like), using color AGV right path for identification.)

This MATLAB Code plot the aperture efficiency Vs the subtended angle. The user determine the value of n and the code plot and tell what is the angle value that achieves max efficeiency and the value of this efficiency.

RLS adaptive filter

hilbert-huang 变换分析一段脉搏波 运行maihht即可(hilbert- KE3 transform a pulse wave can run maihht)

说明：  matlab解决优化问题的一个实验，有ppt说明，matlab入门的好资料(matlab solve the optimization problem of an experiment, a ppt notes, matlab good data entry)

实现分水岭分割，并能对分割结果进行合并，从而有效抑制了分割效果。(Watershed segmentation, and segmentation results of the merger, which effectively inhibited the segmentation results.)
