cupy.linalg.matrix_rank#

cupy.linalg.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.

Return type:

cupy.ndarray
