端口扫描器。 本扫描器实现了：TCP Connect 扫描，TCP SYN扫描，TCP Fin扫描，TCP ACK扫描及UDP端口扫描,这些扫描能够实现扫描特定IP地址范围内端口和扫描某IP地址范围内全部主机特定端口两种模式，并且SYN扫描能够区分端口开放、端口关闭和被防火墙过滤三种状态。(Port scanner. The scanner realized: TCP Connect Scan, TCP SYN Scan, TCP Fin Scan, TCP ACK scan and UDP port scan, the scan can scan a specific IP address range of ports and scanning a range of IP addresses all host two specific ports mode, and can distinguish SYN scan open ports, port closed and the three states firewall filters.)

网上找来的共享的资源，结合matlab和C对图像进行灰度形态学的变换，为进一步的处理做准备。(Online recruited to shared resources, combined with matlab and C of the image gray-scale morphology of the transformation, in preparation for further processing.)

研华数据采集的一个的demo文件，很好用，可以作为里程看，也可以作为现场采集数据的一个简单程序(Advantech data acquisition a demo file, very easy to use, you can see as mileage, can also be used as the data collected at the scene of a simple progra)

用c++求折线的长度，程序可以改变输入点的个数,包含所有的代码.(C++ line with the length requirements, the program can change the number of input points, including all of the code.)
