simulations

国外写的meanshift找聚类中心和类别数目的源程序，有实例，可直接使用(Meanshift looking abroad to write the number of cluster centers and the type of source, there are instances, can be used directly)

书上的matlab编写的PSO算法的例子，可以给初学者借鉴(Books written on the PSO algorithm matlab example, beginners can learn)

说明：  用matlab程序FDTD算法仿真二维光子晶体TM波(FDTD for 2D photonic crystal TM)

高阶谱分析，很实用，能帮助分析非平稳信号(Higher order spectral analysis, it is useful to help analyze non-stationary signals)

关于功率谱估计的,周期图法,自相关法,bartlett法和welch法,还有一个复倒谱估计的代码(On the power spectrum estimation, periodogram, since the relevant law, bartlett law and Welch law, there is a Complex Cepstrum estimated code)

说明：  用MATLAB编程实现OFDM调制，使用了FFT和IFFT方法(Programming with MATLAB realize OFDM modulation, the use of FFT and IFFT methods)

C均值算法的实现，这是我正在学习的C均值算法的实习代码，分享给大家，不当之处，欢迎指正(C-means algorithm, which I am learning C-means algorithm internship code for everyone to share, inappropriate, please correct me)

输入输出程序，用于观察模型的控制效果，并进行响应分析。(Input and output program for controlling the effect observed models and response analysis.)

Radon transform and inverse radon , and their histogram step by step. can be use for edge detection and finding the number of object in image

利用最优阀值法对图像进行分割，自己进行了改进，能够很好的对图像进行分割。(Using the optimal threshold method of image segmentation, improved themselves, can be a good image segmentation.)
