基于802.11a协议的OFDM程序 matlab，很有用哦(OFDM-based 802.11a protocol procedures matlab, oh, very useful)

由一张图像提取圆形的边缘,得到离散的点来拟合椭圆,并简单的去除噪声,得到椭圆中心坐标.(Extracted by a picture rounded edges to fit the discrete points oval, and simply remove noise, get the coordinates of the center of the ellipse.)

说明：  通过矢量积的方式计算6R自由度机器人的雅可比矩阵。通过Matlab的脚本文件，将机器人的DH参数写在脚本开始出，修改此处可以修改机器人参数。(The Jacobi matrix of 6R degree of freedom robot is calculated by vector product. Through the Matlab script file, the robot's DH parameter is written on the script to start out, modify here, you can modify the robot parameters.)

Scale Invariant Feature Transform (SIFT) has shown to be very powerful for general object detection/recognition. And recently, it has been applied in face recognition. This is the matlab code.
