? 2d Gaussian noise in MatLab
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?
Thanks,
