稀疏表示，字典生成例程

c均值算法的实现，使用c均值算法对一组三位数据进行聚类，给出了测试的类别数目和初始值。(c-means algorithm, using the c-means algorithm on a set of three data clustering, given the number of categories and initial value of the test.)

遗传算法工具箱（谢菲尔德大学开发），雷英杰编著的那本书例题全有(Genetic algorithm toolbox (developed at the University of Sheffield))

仿真poisson distribution(Simulation poisson distribution)

说明：  一个自适应算例 根据节点编号的变换找出转换矩阵(Example is based on an adaptive transformation to identify the node number of transformation matrix)

张正友平面相机标定法，使用MATLAB编写，程序全面(Zhang Zhengyou plane camera calibration method using MATLAB.)

利于MATLAB实现OFDM的发送和接收，具体过程发送端先通过QPSK调制，之后进行IFFT变换，然后再添加循环前缀，接收端是一个逆过程。该程序还有另外一个的功能是信道估计，最小乘与卡尔曼滤波器的比较。(MATLAB is helpful to realize the sending and receiving of OFDM. The sending end of the specific process is firstly modulated by QPSK, followed by IFFT transformation, and then cyclic prefix is added. The receiving end is an inverse process. Another function of the program is channel estimation, least - multiplication and kalman filter comparison.)

根据所给定的节点值和节点上的函数值,取边界条件为 “左右两端的一阶导数值为零”, 编制构造三次样条函数的 Matlab 程序。 另附测试程序(Depending on the value of a given node and the node function value, taking the boundary conditions for the " right and left ends of the first derivative value of zero," the preparation of structural cubic spline function of Matlab procedures. Attached test program)

mean shift的两个代码，我已经实现了，有需要的可以看看效果。。。首先是将rgb图转换成lab图，然后再利用mean shift进行分割，最后将分割结果进行二值化。

二维光子晶体，Tm模式，PML边界条件，点源扩散，总场边界场(Two-dimensional photonic crystal, Tm model, PML boundary conditions, point source diffusion, the total field boundary field)

说明：  太阳能发电系统仿真模型，供大家参考学习和使用。(soalr energy system simulation)
