Matlab-and-C-mixed-programming

这是一个我们平时的作业，里面的内容是关于MATLAB的，希望大家觉得有用(This is one of our normal operations, which the content is on the MATLAB, and hope you find it useful)

说明：  文章编辑系统，输入一页文字，程序可以统计出文字、数字、空格的个数。 静态存储一页文章，每行最多不超过80个字符，共N行 (Article editing system, input a word, the program can be worked out, words, numbers, the number of spaces. Static storage an article, each line no more than 80 characters, a total of N rows)

本程序可以显示模拟信号(this program will show an analog signal)

使用MATLAB对数字信号进行中值滤波，尤其可以对图像进行滤波处理(Use MATLAB digital signal filtering, in particular, the image can be filtered)

在偏微分方程的数值求解中，有一类很重要的问题就是求解有奇异点的泊松方程，此程序是用C写的并行程序，能极大的提高泊松方程的求解(In the numerical solution of partial differential equations, there is a class of very important issues that have a singular point of solving the Poisson equation, this program is written in C parallel programs, can greatly improve the solution of the Poisson equation)

说明：   有一个长度为整数L(1<=L<=10000)的马路，可以想象成数轴上长度为L的一个线段，起点是坐标原点，在每个整数坐标点有一棵树，即在0,1,2，...，L共L+1个位置上有L+1棵树。 现在要移走一些树，移走的树的区间用一对数字表示，如 100 200表示移走从100到200之间（包括端点）所有的树。 可能有M(1<=M<=100)个区间，区间之间可能有重叠。现在要求移走所有区间的树之后剩下的树的个数。 输入： 两个整数L(1<=L<=10000)和M(1<=M<=100)。 接下来有M组整数，每组有一对数字。 输出： 可能有多组输入数据，对于每组输入数据，输出一个数，表示移走所有区间的树之后剩下的树的个数。(Has a length of integer L (1 &lt = L &lt = 10000) of the road, one can imagine a number line segment of length L, the starting point is the coordinate origin, each integer coordinate points in a tree, i.e. 0,1 , 2, ..., L total has L+1 L+1 positions on the tree. Now to remove some trees, tree removed by a range of digitally represented, such as 100 200 represents removed (inclusive) between 100 and 200 all the trees. There may be M (1 &lt = M &lt = 100) intervals, there may be overlap between the intervals. Now, after the number of trees require the removal of all remaining sections of the tree. Input: two integer L (1 &lt = L &lt = 10000) and M (1 &lt = M &lt = 100). Then there is an integer M groups, each with a pair of numbers. Output: there may be multiple sets of input data, for each set of input data, the output of a number indicating the number of the removal of all remaining sections of the tree after tree.)

说明：  光学夫朗和费衍射现象模拟Matlab源代码 (Optical phenomenon of Fraunhofer diffraction simulation Matlab source code)

计算三维数据的法矢量并进行调整，里面包括了自己做的实验数据和结果-(The method to calculate the three-dimensional vector data and make adjustments, which includes the experimental data and the results of their own-)

使用MATLAB中的COM生成器(comtool),将M文件生成DLL,于VB中引用.从MATLAB6.5开始,MATLAB提供了COM生成器,使用该生成器,可以将MATLAB函数和自定义的函数打包成组件,然后集成到支持该技术的应用程序中去.使用该技术,可以很大程度上脱离MATLAB环境. (The use of MATLAB)

i am testing. pls check and try to know clearly about this code
