By the way:
% Simpler:
% sigma0 * sqrt(2) ^ (1/level) ^ ((i-1)*level+j)
sigma0 * sqrt(2) ^ (i - 1 + j / level)
With a proper indentation the code looks cleaner: Ctrl-A Ctrl-I

Neither the inner nor the outer loop can be vectorized. The two imshow commands are impossible to vectorize. Do you really need them? Do you want a vectorization to increase the speed? Then start with using the profiler to find the most time consuming part of the code.

What do you want to implement on GPU exactly? imshow, subplot, fspecial are not suitable for this, but conv2 will be fine.
