该matlab代码是一个函数。它接受频域电磁场二维空间分布（用矩阵表示），包括幅度和相位，返回avi文件，显示二维电磁场的动画。(The code is a matlab function. It accepts frequency domain two-dimensional spatial distribution of electromagnetic field (with matrix), including the amplitude and phase, back avi files, the animation shows two-dimensional electromagnetic fields.)

说明：  这是一个用来计算给定IMF分量的瞬时频率的模块(The module that calculates an instantaneous frequency for a given IMF)

一种用于非线性降维的流形学习算法，主要是先考虑用每一点处的局部切空间表示该点处的几何特征，然后都局部切空间进行排列(A manifold learning algorithm for nonlinear dimension reduction, mainly consider to use every bit of the local tangent space representation of geometric feature at that point, then the local tangent space alignment )

一个在MATLAB上编写的PCNN去除噪声的程序源代码完整，可直接使用。(Written in MATLAB on a PCNN noise removal complete source code can be used directly.)

说明：  有EEMD分解的源程序，可求解分量信号的能量熵(Source program containing EEMD to solve the energy entropy of component signals)

CDMA系统的编码和解码的MATLAB源程序(code and decode of CDMA system)

说明：  遗传算法，prufer编码解决最小生成树问题(GA)

说明：  车牌识别程序,将文件放于matlab目录下work文件夹中运行(License plate recognition program, the files placed in the matlab directory to run under the work folder)

一、CORBA原理 二、Orbix 2000与ART 三、CORBA标准服务 四、成功案例 五、应用开发讨论(1, CORBA Principle 2, Orbix ART 2000 with three, four CORBA standard services, five successful cases, application development discussion)

判别方法，支持向量机与马氏距离判别法，用在可见及近红外光谱分析上百分之一百可以，自己写的，最好是matlab2014a，这个版本可以使用(Discriminant method, support vector machine (SVM) with markov distance criterion, with one hundred percent in the visible and near infrared spectrum analysis, write their own, had better be matlab2014a, this version can be used)
