Matlab-senior-notes(3)

交错网格声波方程正演模拟，交错网格有限差分地震波场计算，二维的声波正演，利用空间10阶，时间2阶。(The CalCulation of the SeismiC Wave一 fieldwith Staggered-grid Finite difference Sheme)

说明：  一个MATLAB的应用程序，很方便的！使用时需要转换为M文件。(a MATLAB applications, a convenient! Use need to change for the M documents.)

matlab演奏《最炫民族风》音乐的程序代码3(matlab music code3)

⑴.设计游乐平面图，所含景点不少于10个。以图中顶点表示游乐园各景点，存放景点名称、代号、等信息；以边表示路径，存放路径长度等相关信息。 ⑵．为游人提供图中任意景点的问路查询，及查询任意两个景点之间的一条最短的简单路径。 (⑴. Designed to play plan, contained less than 10 scenic spots. To graph vertices, said the amusement park attractions, attractions store names, codes, and other information to edges, said path, the path length of storage of information. ⑵. To provide the figure for the visitors ask for directions any spots, queries, and query any two attractions of a shortest simple path.)

Calendar conversiono为日历转换代码，可以将阳历转变为阴历，也可将阴历转变为阳历(Calendar conversiono for the calendar conversion code, can be transformed into the lunar solar calendar lunar calendar, also can be converted to the Gregorian calendar )

说明：  支持向量机的C++源代码包，用机器学习的方法处理优化问题，可以作为matlab的工具箱。(C++ code for proceeding SVM problems！)

自己编写的matlab简单计算，用于计算矩阵的加减乘与求逆，特征行列式等(I have written matlab simple calculation used to calculate the matrix addition and subtraction, multiplication and inversion, characteristic determinant, etc.)

Visual C++编程实现Kalman滤波器(It realize the Kalman filter with visual c++)

此函数是用C语言编写的MEX文件，与MATLAB中imreconstruct函数功能相同，效果一样，运行速率更快。(This function is written in C MEX file, the same function with in MATLAB imreconstruct function, the same effect faster run rate.)

利用非线性控制完成光伏并网逆变器的设计，设计中采用模糊控制和反步法，介绍很好。(Using nonlinear control to complete the design of the photovoltaic (pv) grid inverter, adopted in the design of advanced reverse moves, the introduction is very good.)
