SALSA的MATLAB相关编码和源程序(SALSA in the MATLAB source code and related)

使用神经网络实现对函数sin(x1)/x1*sin(x2)/x2的模拟，代码为matlab代码，输入为二维数组，输出为一个数，结果误差为0.225左右,(Using neural networks to function sin (x1) Analog/x1* sin (x2)/x2, the code for matlab code, enter a two-dimensional array, the output is a number, the result error is about 0.225,)

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 )
