![]() |
Tests whether a value's _applyunitary is correct.
cirq.testing.assert_has_consistent_apply_unitary_for_various_exponents(
val: Any,
*,
exponents=(0, 1, -1, 0.5, 0.25, -0.5, 0.1, sympy.Symbol('s'))
) -> None
Contrasts the effects of the value's _apply_unitary_
with the
matrix returned by the value's _unitary_
method. Attempts this after
attempting to raise the value to several exponents.
Args | |
---|---|
val
|
The value under test. Should have a __pow__ method.
|
exponents
|
The exponents to try. Defaults to a variety of special and
arbitrary angles, as well as a parameterized angle (a symbol). If
the value's __pow__ returns NotImplemented for any of these,
they are skipped.
