- ak._v2.ak_argcombinations.argcombinations(array, n, replacement=False, axis=1, fields=None, parameters=None, with_name=None, highlevel=True, behavior=None)¶
array – Array from which to choose
nitems without replacement.
n (int) – The number of items to choose from each list:
2chooses unique pairs,
3chooses unique triples, etc.
replacement (bool) – If True, combinations that include the same item more than once are allowed; otherwise each item in a combinations is strictly unique.
axis (int) – The dimension at which this operation is applied. The outermost dimension is
0, followed by
1, etc., and negative values count backward from the innermost:
-1is the innermost dimension,
-2is the next level up, etc.
fields (None or list of str) – If None, the pairs/triples/etc. are tuples with unnamed fields; otherwise, these
fieldsname the fields. The number of
fieldsmust be equal to
parameters (None or dict) – Parameters for the new
ak.layout.RecordArraynode that is created by this operation.
with_name (None or str) – Assigns a
"__record__"name to the new
ak.layout.RecordArraynode that is created by this operation (overriding
parameters, if necessary).
highlevel (bool) – If True, return an
ak.Array; otherwise, return a low-level
Computes a Cartesian product (i.e. cross product) of
array with itself
that is restricted to combinations sampled without replacement,
ak.combinations, but returning integer indexes for
