该程序简单的仿真了OFDM系统，包括信号的产生，映射，调制，加噪，解调(The program is simple simulation of the OFDM system, including signal generation, mapping, modulation, noise, demodulation)

此源码为进行手写文字识别的Matlab经典算法的实现，希望能对大家有所帮助(This source for handwritten character recognition algorithm of the Matlab classic realize the hope that it can be helpful to everyone)

张正友相机标定程序 张正友摄像机标定法是一种简单实用的标定法，本次试验中共取用了同一摄像机从不同角度拍摄的六幅图像，经过Harris角点提取并优化从每幅图像中取十个特征点来进行摄像机标定（这十个点的世界坐标相同）。(Zhang Zhengyou camera calibration procedure Zhang Zhengyou camera calibration method is a simple and practical calibration method, this test CCP access to the six images of the same camera taken different angles, through Harris corner extraction and optimization take ten each image camera calibration feature points (the same world coordinate these ten points).)
