How can I improve the time for the next code?. Basically, I want to solve a
large undetermined binary linear system and then I need to calculate its
hamming weight.
A = random_matrix(GF(2), 10, 12, density=0.55)
b = random_vector(GF(2), 10)
particular_soln = A.solve_right(b, check=False)
A_right_kernel = A.right_kernel()
for homogeneous_soln in A_right_kernel:
v = (particular_soln + homogeneous_soln)
print len(v.nonzero_positions())
