计算电磁学 二维廖氏吸收边界程序 采用MATLAB编写(Lio dimensional computational electromagnetics absorbing boundary program written using MATLAB)

线性时不变离散时间系统在时域中可以通过常系数线性差分方程来描述，冲击响应序列可以刻画其时域特性。本实验通过使用MATLAB函数研究离散时间系统的时域特性，以加深对离散时间系统的差分方程、冲激响应和系统的线性和时不变特性的理解。(The linear time-invariant discrete-time system can be described in the time domain by a linear difference equation with constant coefficients. The impulse response sequence can describe its time-domain characteristics. This experiment uses MATLAB functions to study the time domain characteristics of discrete-time systems to deepen the understanding of differential equations, impulse response, and linear and time-invariant characteristics of the system.)

MATLAB编写的一个M文件，实现二分法求函数f在[a,b]上的一个零点，牛顿插值法(MATLAB prepared a document M, realize dichotomy for function f in [a, b] a zero, the Newton interpolation)

The function takes three input arguments (function and two initial guesses belonging to the interval). After iterations, it returns the root of the function. The fourth input argument is to change the stopping criteria of the loop.

Matlab 工具箱，基于正则期望最大化方法(Regularied Expectation Maximization)的数据填充。(A Matlab toolbox based on the regularied expectation maximization (RegEM) based data imputation.)

基于多相结构的信道化接收机，包含特征值与特征向量的提取、训练样本以及最后的识别，自写曲率计算函数 。( Channelized receiver based on multi-phase structure, Contains the eigenvalue and eigenvector extraction, the training sample, and the final recognition, Since writing the curvature calculation function.)

说明：  一个MATALAB写的SOM神经网络原代码程序(a MATALAB write SOM neural network source procedures!)

一个主流卡尔曼滤波的运动目标跟踪程序，也可以作为卡尔曼滤波应用的一个参考(A matlab code for movement target tracking based Kalman filter , also it can be used as a reference of the application of the Kalman filter )

用matlab绘制面积图的例子程序，还不错哦。(draw area plot using matlab)
