Use graphs' covariance matrix to sample from a GBS

I’m wondering as well if this solution is what’s needed in one of your other posts too!

Problem in sf.apps.similarity.prob_orbit_exact() function

Hey! Apologies for that, Here you go! def probzu(A,S): #A is the adjacency matrix of the graph and S is the sample p=1 k= np.repeat(A, S, axis=0) A1= np.repeat(k, S, axis=1) #A1 is An of the paper where the rows and columns are repeated as per the sample z= np.abs(haf(A1)) ** 2 #The hafnian calculation of An _, s, _ = np.linalg.svd(A, full_matrices=True) c = 1 / ( np.max(s) + 1e-8 ) #Calculation of the maximum singular value of A Ab = c * np.block([ #Calcula…
