I have contributed 40 objective type c questions written as source code. Which will be helpful in learning C.

9节点前推回代法潮流计算，基本潮流！源程序(9 nodes forward and backward substitution method flow calculation, the basic trend! Source)

空间矢量调制基本原理与DSP实现，一看就懂，可仿真验证(The basic principle of space vector modulation and DSP implementation, one can understand, can simulation)

MIT心电数据库读取程序源码 MIT的格式不能直接在MATLAB上使使用 通过此程序源码转换成能直接应用在MATLAB上的格式 可直接使用。 (MIT ECG database reads the program source MIT' s format can not be converted to make use of this program source code can be applied directly in MATLAB format can be directly used directly in MATLAB.)

MATLAB (matrix laboratory) is a numerical computing environment and fourth-generation programming language. Developed by MathWorks, MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages, including C, C++, Java, and Fortran.(MATLAB是MATrix LABoratory的缩写，是一款由美国MathWorks公司出品的商业数学软件。MATLAB是一种用于算法开发、数据可视化、数据分析以及数值计算的高级技术计算语言和交互式环境。除了矩阵运算、绘制函数/数据图像等常用功能外，MATLAB还可以用来创建用户界面及与调用其它语言（包括C，C++和FORTRAN）编写的程序。)

DCT域分布式视频编码经典MMSE重建C++代码(DCT Distributed video coding tipal MMSE recostruction C++ code)

本代码是Real-time O(1) Bilateral Filtering,也就是常数时间复杂度的双边滤波器，它对于很多其他算法有着很大的作用。对应论文就是Real-time O(1) Bilateral Filtering。亲自编译运行通过(It is the C++ code of Real-time O(1) Bilateral Filtering, that is, constant time complexy bilateral filtering, it is vitally useful for other algorithams. The responding paper is Real-time O(1) Bilateral Filtering. It is execuable.)

软件代码保护编写方法-vmprotect(soft-code protect writing-vmprotect)

说明：  约瑟夫问题的实现：设有n个人围坐在圆桌周围，现从某个位置m（1≤m≤n）上的人开始报数，报数到k的人就站出来。下一个人，即原来的第k+1个位置上的人，又从1开始报数，再报数到k的人站出来。依此重复下去，直到全部的人都站出来为止。试设计一个程序求出出列序列。(Joseph realized the problem: There are n people sitting around the round table, is from a position of m (1 ≤ m ≤ n) reported on the number of people began to be reported to the k number of people to come forward. The next person, that is, the original positions on the first k+1 people, and from the number reported at 1, then the number reported to the k to stand up. So repeat this until all the others can stand up. Try to design a program derived from the column sequence.)

这个是关于matlab仿真OFDM的完整程序，可以很好的掌握哦对于初学者(the study of OFDM using matlab)
