非线性 matlab Nonlinear system_Hassan_K_Khalil的matlab代码。书本的代码编写主要集中在第二章，第十三章，第十四章代码(the matlab code of Nonlinear system_Hassan_K_Khalil, the code main are in the charpter 2 ,charpter 13 and charpter 14)

matlab7图书里面的所有matlab代码，对初学者很有用，可以用来来纳西基本操作，熟悉基本的子程序，或供工程人员进行功能仿真是很的参考(Book inside matlab7 all matlab code, very useful for beginners and can be used to Naxi basic operation, familiar with the basic subroutine, or by project team members to conduct functional simulation is the reference)

自己写的程序，光栅中线性啁啾仿真，分析光栅特性很有用，(Write their own programs, the linear chirp grating simulation, analysis Gratings useful)

说明：  一个4阶的切比雪夫Ⅰ型低通滤波器，可以用它对信号进行滤波。当然，滤波器的零极点图也是必不可少的。(A 4-order Chebyshev low-pass filter of type Ⅰ, you can use it to filter the signal. Of course, the filter pole-zero map is essential.)

说明：  加椒盐噪声，二维高斯低通滤波器，计算二维线性滤波(Add salt and pepper noise, Gaussian low-pass filter to calculate two-dimensional linear filtering)
