this contains simulated model of 3 phase inverter in 180 degree mode

MATCOM提供了MATLAB到C++的编程接口，本文是MATCOM4.5的说明文档，详细介绍了MATCOM的各个函数和操作符等。(MATCOM MATLAB to C++ provides a programming interface, this article is MATCOM4.5 documentation, detailing MATCOM various functions and operators and so on.)

this code uses newtons method but in the form for function to solve non linear equations. use all the file available in the rar file to run the code.

数字图像处理，冈萨雷斯著，一本很好的书，值得一看！而且本书为MATLAB版本，很具有参考价值。(Digital Image Processing, Gonzalez' s book, a very good book, worth a visit! And for the MATLAB version of the book, it is a reference value.)

说明：  带有收缩因子和惯性权重的基本PSO粒子群算法源代码。本源代码模块化编写，结构清晰，便于改进和做数值实验(With contraction factor and inertia weight PSO basic particle swarm algorithm source code. Source code modular preparation, structure, clear, easy to improve and to do numerical experiments)

三阶锁相环频率合成器的simulink 模型，可以演示三阶锁相环工程过程，验证参数合理性(Three phase lock loop )

已知轴线方程,把圆柱按轴线分若干段，在每个断面画圆，圆的法线就轴线的切向方向。柱面画若干平行于轴线的线条，其中用到平行单位矢量点积等于1，不平行的结果是[-1，1）。 (Axis equations are known, according to the axis of the cylinder divided into several segments, each section in the circle, the circle axis normal to the tangential direction. Number of cylinders parallel to the axis of drawing lines, which use the parallel unit vector dot product is equal to 1, the result is not parallel to [-1,1). )

kalman滤波算法的分析设计，首先分析设计模型，再进行初始化，最后进行kalman迭代计算，得到结果(kalman filter algorithm analysis and design, analysis and design models first, then initialized, and finally the kalman iterative calculations, the results)

一个非常好的图像恢复的工具集，matlab编写的源代码。(A very good image restoration tools, matlab prepared source code.)
