# cirq.is_orthogonal¶

cirq.is_orthogonal(matrix: numpy.ndarray, tolerance: cirq.linalg.tolerance.Tolerance = Tolerance(rtol=1e-05, atol=1e-08, equal_nan=False)) → 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. tolerance – The per-matrix-entry tolerance on equality. Whether the matrix is orthogonal within the given tolerance.
