这个程序是用来绘制光子晶体光纤的色散曲线。(This program is used to draw the dispersion curves of the photonic crystal fiber.)

Using Chan-Vese model to segment 2D image (Using Chan-Vese model to 2D image segment)

实现对函数的步长加速法寻优，并作图直观显示寻优过程和效果(The step function to achieve acceleration method optimization and mapping visual display optimization process and effects)

机械画图，曲柄摇杆机构，用matlab实现的，希望大家喜欢(Mechanical drawing, crank rocker mechanism, using matlab to achieve, I hope you like)

说明：  电磁波在含有磁场的等离子体中的传输；磁感应强度可以变化(microwave propagation in magnetic plasma)

产生余弦的四种相位竖条纹，做三维形貌测量用。(Cosine of zero-phase vertical stripes, three-dimensional shape measurement)

一个由matlab编写的从多视点拍摄的图像计算Visual Hull的简单的演示程序，基于空间体积的方法求物体的Visual Hull，对实现由多视点图像求Visual Hull的过程可以起到借鉴作用(Matlab prepared by a multi-viewpoint images of the Visual Hull calculate simple demo program, the method of space-based volume objects for Visual Hull, the realization of multi-viewpoint image for Visual Hull of the process can play a useful reference)

说明：  本方法采用pca进行特征提取，knn分类器进行人脸识别。(The method of feature extraction using pca, knn classifier for face recognition.)

通过MATLAB程序可以很容易的画出三维的图像，让初学者一目了然。(MATLAB program can easily draw a three-dimensional image, so that beginners at a glance.)
