Python Vector.basis Examples

Example #1

def test_basis_creation():
    assert Vector.basis(0, 2) == Vector(1, 0)
    assert Vector.basis(3, 6) == Vector(0, 0, 0, 1, 0, 0)

Example #2

def test_vector_splitting_to_basis_products():
    product_vector = Vector.zero(len(a))
    for i, component in enumerate(a):
        product_vector += Vector.basis(i, len(a)) * component

    assert product_vector == a
