Python calc_pi_from_data Examples

Example #1

def test_stride_pi(lorenz_dataset):
    _, _, X, _, _ = lorenz_dataset
    X = X[:, :3]
    pi = calc_pi_from_data(X, 4)
    pi2 = calc_pi_from_data(X, 4, stride=2)
    assert pi != pi2
    pi2 = calc_pi_from_data(X, 4, stride=.5)
    assert pi != pi2

Example #2
