matlab仿真Markov机制转换模型(The Markov Regime Switching Package for Autoregressive Models)

用基于 Matlab 的小容量 FFT (比如 256×256)程序，将取样窗口划分为 若干个全等的小矩形,对每个小矩形内离散点的复振幅作 FFT 变换,然后将所有变 换结果叠加，再乘以复数相位因子,相当于对整个物面上点进行菲涅耳衍射计算， 利用这种方法可以迅速的实现高精度的轴对称傍轴光学系统中的激光衍射计算 (With a small volume based on Matlab FFT (eg 256 × 256) procedure to sample window divided into a number of small identical rectangles, each small rectangle of discrete points within the complex amplitude for the FFT transform, and then transform the results of all the superposition multiplied by the complex phase factor, the equivalent point on the object plane Fresnel diffraction calculation, the use of this method can rapidly achieve high-precision optical system axis of symmetry in the paraxial calculation of laser diffraction)

空间电压矢量调制技术模块，进过自己认真仔细的搭建，可用。(Space vector modulation module, has been to carefully build available.)

这是我自己搭建的射频中经常用到的T型滤波器，希望对大家有所帮助！(This is my own radio frequency often used to build a T-type filter, we want to help!)

多维K-means聚类：空间数据分析中最常用的是聚类分析,而K-MEANS算法是聚类分析中常用的,其主要思想是在给定的聚类数目下对多维(我做的是三维空间点)向量进行聚类(aClus.Center.x=m_vecExtreCenter[i].extrePoint.x; aClus.Center.y=m_vecExtreCenter[i].extrePoint.y;)

Permanence脉冲微分方程程序用matlab模拟种群的灭绝和持续生存(Permanence Impulsive Differential Equation Program Using matlab to Simulate the Extinction and Persistence of Population)

说明：  计算SSIM的matlab相关的代码,通过它可求两张图片的结构相似度(cal ssim,which can calculate the ssim between two images)
