5.3 维纳滤波法

插值与拟合，griddataexam，matlab经典算法的程序 数学类(griddataexam)

该MATLAB程序实现了simplex迭代算法，该算法可以在不对目标函数求导情况下进行优化，适合数据量较大的算法优化。(The MATLAB program to achieve a simplex iterative algorithm, which can be optimized in the right objective function derivation, the large amount of data suitable algorithm optimization.)

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 )
