scipy.sparse.coo_matrix.argmax#
- coo_matrix.argmax(axis=None, out=None)[source]#
Return indices of maximum elements along an axis.
Implicit zero elements are also taken into account. If there are several maximum values, the index of the first occurrence is returned.
- Parameters
- axis{-2, -1, 0, 1, None}, optional
Axis along which the argmax is computed. If None (default), index of the maximum element in the flatten data is returned.
- 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
- indnumpy.matrix or int
Indices of maximum elements. If matrix, its size along axis is 1.
