# 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
