matrix_rank
(M, tol=None)[source]¶ Return matrix rank of array using SVD method
Parameters: - M (cupy.ndarray) – Input array. Its ndim must be less than or equal to 2.
- tol (None or float) – Threshold of singular value of M.
When tol is None, and eps is the epsilon value for datatype
of M, then tol is set to S.max() * max(M.shape) * eps,
where S is the singular value of M.
It obeys
numpy.linalg.matrix_rank()
.
Returns: Rank of M.
