is_special_unitary(matrix: numpy.ndarray, *, rtol: float = 1e-05, atol: float = 1e-08) → bool¶
Determines if a matrix is approximately unitary with unit determinant.A matrix is special-unitary if it is square and its adjoint is its inverseand its determinant is one.
matrix – The matrix to check.
rtol – The per-matrix-entry relative tolerance on equality.
atol – The per-matrix-entry absolute tolerance on equality.
Whether the matrix is unitary with unit determinant within the given tolerance.
