MATLAB科学计算与可视化仿真宝典源代码，从第一章到第27章(MATLAB simulation of Scientific Computing and Visualization Collection source code, from the first chapter to Chapter 27)

三机九节点电力系统牛顿法潮流计算与短路计算算例编程(Three machine nine-bus power system, Newton' s method flow calculation and short circuit calculation example programming)

绘制庞加莱截面图 在相空间中适当（要有利于观察系统的运动特征和变化，如截面不能与轨线相切，更不能包含轨线）选取一截面，在此截面上某一对共轭变量如x1和x.1取固定值，称此截面为Poincare截面，相空间的连续轨迹与Poincare截面的交点成为截点。(Poincare mapping sections in the phase space properly (should be beneficial to observe the system and changes in movement characteristics, such as the cross-section can not be tangent trajectory, but also can not contain rail line) to select a cross-section, in this section for a total of conjugate variables, such as x1 and X.1 take a fixed value, call this cross-section for the Poincare section, the phase space of the continuous trajectory of the point of intersection with the Poincare cross-section to become cut-off point.)

per-task delay accounting.

是整个光上OFDM的仿真，有清晰地注释，方便读者自己理解。(Is the entire OFDM simulation on the light, clearly comment, the convenience of the reader understand.)

To develop functional modules to process grayscale image intensity data. And perform Point and spatial operations. Uses Prewitt, Sobel, and Laplacian of Guassian Methods. And calculates their histograms. (To develop functional modules to process grayscale image intensity data. And perform Point and spatial operations.

说明：  三维圆柱曲线的绘画matlab程序。很方便。(3D Plot on a Cylindrical Surface)

目前已经提出了许多不同的算法来解决OFDM 系统中的PAPR 问题，本章详 细介绍了其中的限幅法、压缩扩张法、星座图扩展法、选择性映射法和部分传输 序列法。在介绍每一种算法时，针对其主要存在的问题进行了相应的改进，使每 一种算法都成为比较实用的算法。(Has put forward a number of different algorithms to solve the problem PAPR OFDM system, this chapter details Fine describes one of the limiting, compression expansion method, constellation expansion method, selective mapping method and partial transmission Sequence method. In introducing each algorithm, for which the main problem for the corresponding improvements, so that each An algorithm have become more practical algorithms.)

说明：  Matlab下面的支持向量机的程序包。。应用范围很广(Matlab following SVM package. . Application very wide scope. .)
