Finite element method introduction in matlab

EM 算法是求参数极大似然估计的一种方法，它可以从非完整数据集中对参数进行估计，是一种非常简单实用的学习算法。这种方法可以广泛地应用于处理缺损数据、截尾数据以及带有噪声等所谓的不完全数据，可以具体来说，我们可以利用EM算法来填充样本中的缺失数据、发现隐藏变量的值、估计HMM中的参数、估计有限混合分布中的参数以及可以进行无监督聚类等等。(Expectation Maximization image segmentation Input: ima: grey color image k: Number of classes Output: mask: clasification image mask mu: vector of class means v: vector of class variances p: vector of class proportions )

xPC Target 工具箱使你可以在 Simulink 的框图中加入 I/O 方块图，并用 RTW 产生代码，最后下载到另一个运行 xPC Target 实时内核的 PC 机上。对于控制和 DSP 系统来说 xPC Target 是理想的快速原型和硬件在回路测试工具，它可以使你在一台标准的 PC 机上运行实时模型。如果附加 xPC Target 嵌入模块选项，你可以把你的实时嵌入式系统放入到一台微机上，应用于生产、数据采集、标定和测试应用程序等过程中。 (xPC Target toolbox allows you to add in the Simulink block diagram of the I/O block diagram, and use RTW generated code, and finally downloaded to another running xPC Target real-time kernel of the PC machine. For the control and DSP systems is ideal for the xPC Target rapid prototyping and hardware in the loop testing tool that allows you to a standard PC, running real-time model. If the additional xPC Target Embedded Module option, you can put your real-time embedded systems to a microcomputer applied to the production, data acquisition, calibration and test applications such as process. )

用matlab/m文件编写的计算标准大气压小程序，非常实用，可以用于各种飞行器控制设计等方面的仿真，m文件编写很容易转换成c/c++，有问题请留言。(Written using matlab/m file calculation standard atmospheric pressure of small procedures, very useful, can be used for simulation of various aircraft control design, m document can be easily converted into c/c++, have any questions please leave a message)

一种新的协同进化优化算法处理图像的方法，很好，能运行！！( A new coordination method, image processing algorithm in evolutionary optimization is very good, can run )

David G. Lowe的SIFT特征点检测及匹配源代码，内有自己总结的各文件及参数功能的PPT文档(David G. Lowe' s SIFT feature point detection and matching source code, the summary of each document has its own functions and parameters PPT documents)

设定ARMA模型参数,求所采集到的数据的双谱和特征量（带有测试数据）(Autoagressive Moving Average)

说明：  OQPSK的调制解调程序，希望对初学的你有所帮助 (OQPSK modulation and demodulation process, you want to be helpful for beginners)

说明：  用MATLAB实现7参数转换的小程序，会很方便的(7 parameters using MATLAB to achieve conversion of small programs)
