scipy.sparse.csr_matrix.argmin

csr_matrix.argmin(axis=None, out=None)

Return indices of minimum elements along an axis.

Implicit zero elements are also taken into account. If there are several minimum values, the index of the first occurrence is returned.

Parameters:

axis : {-2, -1, 0, 1, None}, optional

Axis along which the argmin is computed. If None (default), index of the minimum element in the flatten data is returned.

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.

Returns:

ind : np.matrix or int

Indices of minimum elements. If matrix, its size along axis is 1.
