cirq.is_orthogonal

cirq.is_orthogonal(matrix: numpy.ndarray, *, rtol: float = 1e-05, atol: float = 1e-08) → bool[source]

Determines if a matrix is approximately orthogonal.

A matrix is orthogonal if it’s square and real and its transpose is its
inverse.
Parameters:
  • matrix – The matrix to check.
  • rtol – The per-matrix-entry relative tolerance on equality.
  • atol – The per-matrix-entry absolute tolerance on equality.
Returns:

Whether the matrix is orthogonal within the given tolerance.
