scipy.sparse.csr_matrix.max¶

csr_matrix.max(axis=None, out=None)[source]¶

Return the maximum of the matrix or maximum along an axis. This takes all elements into account, not just the non-zero ones.

Parameters

axis{-2, -1, 0, 1, None} optional: Axis along which the sum is computed. The default is to compute the maximum over all the matrix elements, returning a scalar (i.e., axis = None).
outNone, optional: This argument is in the signature solely for NumPy compatibility reasons. Do not pass in anything except for the default value, as this argument is not used.

Returns

amaxcoo_matrix or scalar: Maximum of a. If axis is None, the result is a scalar value. If axis is given, the result is a sparse.coo_matrix of dimension a.ndim - 1.
