实现dtmf双音多频信号的matlab仿真编码和解码，采用coertzel算法。(Methods of measurement for pushbutton telephone with DTMF )

this is my code which i learnt in image processing lesson. it finds any geometric shape and draw black lines around it which stands on a white background. it could help how to find a shape for new learners in DIP

本设计研究了纠错码及循环冗余校验码的原理，以及利用MATLAB对其进行了编程和编译仿真，实现了CRC循环冗余校验码的编码及校验，在接收端收到通过校验的码.(This design research the error correcting code and cyclic redundancy check code principle, and the use of the MATLAB programming and compile the simulation, realized the CRC cyclic redundancy check code coding and check, at the receiving end received through the check code.)

基于结构可靠度中的响应面法的matlab程序，求解边坡的极限状态方程和可靠概率(Based on structural reliability of the response surface method matlab program, the slope of the limit state equation solving and reliable probability)

CNM算法实现的快速社团检测，方便快捷好用(CNM Fast community detection based on the algorithm is convenient, fast and easy to use.)

用matlabf编程求解通常的图着色问题,经常使用这个原理的.(Matlabf programming is usually used to solve the graph coloring problem, frequent use of this principle.)

背包问题的主函数很有用啊 本程序主要用到遗传算法(背包)
