Design and Use of Steerable Filters PAMI1991文章的代码，含有测试图像和demo，可运行(It implements a steerable Gaussian filter. This m-file can be used to evaluate the first directional derivative of an image, using the method outlined in: W. T. Freeman and E. H. Adelson, "The Design and Use of Steerable Filters", IEEE PAMI, 1991.)

非线性系统的模型阶次辨识+模型系统辨识，非常有效(Model order nonlinear system identification+ model system identification, is very effective)

程序代码说明 P0502：计算图像中的欧拉数(Procedure Code Description P0502: Calculation of image Euler Number)

this code uses the particle swarm optimization PSo techinque in tunning a PID controller in order to obtain the adequate values of the controller gains

利用EEMD进行自适应信号分解，并附赠一个快速样本熵的程序。(EEMD is used for adaptive signal decomposition, and a fast sample entropy program is attached.)

是Grey Method的使用方法，方便好用，欢迎大家下载，如果有问题，也欢迎给我留言，我的QQ号码是：55101(Gray Method is the way to use of convenient and you are welcome to download, if there are problems, I also welcome to voice mail, my QQ number is : 55101)

简单的将线性调频信号的时域图和频域图对比描述，帮助读者更加直观的看出线性调频信号的特征(Simple time domain and frequency domain plots in Figure chirp signal contrast description to help readers see more intuitive chirp signal characteristics)

Solves part b for three values of p: 0.1, 0.3, 0.5, and 0.8. To solve for other values of p, just change the numbers in the vector p below.
