sparse.
where
(condition, x=None, y=None)[source]¶ Select values from either
x
ory
depending oncondition
. Ifx
andy
are not given, returns indices wherecondition
is nonzero.Performs the equivalent of
numpy.where
.Parameters: - condition (SparseArray) – The condition based on which to select values from
either
x
ory
. - x (SparseArray, optional) – The array to select values from if
condition
is nonzero. - y (SparseArray, optional) – The array to select values from if
condition
is zero.
Returns: The output array with selected values if
x
andy
are given; else where the array is nonzero.Return type: Raises: ValueError
– If the operation would produce a dense result; or exactly one ofx
andy
are given.See also
