csc_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.


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).

out : None, 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.


amax : coo_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.
