说明：  通过gamultiobj函数，实现基于nsga2的改进优化算法(An improved optimization algorithm based on NSGA2 is implemented by gamultiobj function)

简单实用的matlab例程，信号方位估计的一种算法(simple but classic matlab algorithm, is the polynomial method to find DOA (Direction of Arrival))

S函数的编写，对于一个学控制的同学和MATLAB的同学很有用的(The preparation of S-function, a learning control for students and the students very useful MATLAB)

傅里叶变换和小波变换重建图像的比较效果，这个程序可以用来实现四个要求：1、FFT和WT重建效果比较；2、通过改变小波来比较重建效果；3、通过改变分解层数来比较重建效果；4、通过改变大系数个数来比较重建效果。其中还有一个计算PSNR的程序(the comparative effect of reconstruction image by Fourier transform and wavelet transform 。 the program can be used to achieve the four requirements: 1, FFT, and WT reconstruction effect 2, by changing the wavelet to compare the reconstruction effect 3, by changing the decomposition layers to compare the reconstruction effect 4, by changing the number of large coefficient of comparative reconstruction results. Including a procedure of calculating PSNR )
