pygsti.tools.matrixtools.columns_are_orthonormal

columns_are_orthonormal(m, tol=1e-07)

Checks whether a matrix contains orthogonal columns.

The columns do not need to be normalized. In the complex case, two vectors v and w are considered orthogonal if dot(v.conj(), w) == 0.

Parameters:

• m (numpy.ndarray) – The matrix to check.

• tol (float, optional) – Tolerance for checking whether dot products are zero.

Return type:

bool
