Beispiel #1

def test_ml_solve_laplace2d_SF():
    A, b, x_exact = example_laplace2d(900)
    param = ilupp.iluplusplus_precond_parameter()
    param.PREPROCESSING.set_SPARSE_FIRST()
    param.threshold = 1e-2
    x, info = ilupp.solve(A, b, atol=1e-8, rtol=1e-8, params=param, info=True)
    print('Convergence info:', info)
    assert np.allclose(x_exact, x)
