能够提取出图像I的HOG特征，返回其幅值，角度和在各个角度上的幅值。 是进行其他针对图像的HOG特征提取的前一步。(I can extract images of HOG features, return to their amplitude, angle and perspective in all of the amplitude. Is the other for image feature extraction HOG step forward.)

系统辨识教材，个人认为很不错，希望对大家有用！(The system identification teaching material, I believe is very good, hoped that is useful to everybody!)

卡尔曼滤波的一个视频跟踪程序，简单实用，希望能帮助大家(Kalman filter tracking of a video program, simple and practical, hoping to help people)

找出数据的规律，然后按照要求，对数据进行分类，使数据清晰明了 (Find out the rules of data, and then follow the requirements of the data classification, so that the data clarity)

很优良的PID控制器设计仿真程序与模型,经过严格检验(Very good simulation of PID controller design procedures and models, to undergo a rigorous inspection)

联合Optisystem与matlab仿真的OFDM子程序(Optisystem & matlab co-simulation)

利用自然梯度算法，实现串口的数据采集，相控阵天线的方向图（切比雪夫加权），仿真效率很高的，进行波形数据分析,这个有中文注释，看得明白。

此代码是求TSP中群蚁问题的全代码，只需对其中的数据进行适当的调整就可以套用(This code is a group of ants seeking TSP problem in the whole code, only the data on which appropriate adjustments can be applied)

说明：  采用白噪声作为输入信号，用递推最小二乘法来进行系统辨识(Using white noise as input signal, using recursive least squares method for system identification)
