Detail of anisotropic gaussian kernel

In the generation of anisotropic gaussian kernel, see

def anisotropic_gaussian_kernel(l, sigma_matrix, tensor=False):

why y is set as y = np.clip(np.random.random() * scaling * x, sig_min, sig_max)? Why don't choose the same way as x = np.random.random() * (sig_max - sig_min) + sig_min?

Great idea!
There are lots of methods to define anisotropic kernel's parameters and their relationship. Here is just one way.
