代码说明:

  em algorithm - Find approximate solution to Sf = conv(s,f) = d using EM iteration. EM seeks to minimize the Poisson negative log likelihood function J(f) = sum_i {[Sf]_i - (d_i + sigma^2)*log([Sf]_i + sigma^2)}.

  • image-construction-by-fft-and-wt
    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 )

    说明:  分数阶热传导工具箱可以用于求解分数阶微分方程中的热传导过程的求解,包含解析解与数值解的求解方式,含有显式,隐式和Crank–Nicolson求解方法。(The methods of solving models of heat conduction are described, namely analytical and numerical methods. In the case of numerical methods regards the finite difference method by using GL definition for the fractional time derivative. Implementation of these individual methods was realized in MATLAB. The two libraries of m-functions for the heat conduction model have been created, namely Heat Conduction Toolbox and Fractional Heat Conduction Toolbox.)
