MATLAB: Creating a frame(image), randn

randn

Hi
Does
a = sqrt(3)*randn(20,20)
imshow(a,([ ]))
create a frame(image), with 20×02 pixels, size of each pixel being 1×1, and the values of the pixels representing a Gaussian with covariance '3', and the intensity of each pixel to be gray linear scale.
Thanks
P

  • No. Try again. By the way, what do you mean by covariance? Do you mean variance or standard deviation instead?
