randn()
rand() randn()都可用n維矩陣
請多看doc
※ 引述《ccos ( )》之銘言：
> MatLab built-in function rand() gives uniform dist random numbers.
> x = rand(10); xgauss = exp( -0.5*( ( x-mu )./std ).^2 )/sqrt(2*pi*std);
> The above gives 1D Gaussian noise. But now I'd like to add Gaussian
> noise to a 2D picture. How do I generate 2D Gaussian noise then?
