- ak.concatenate(arrays, axis=0, *, mergebool=True, highlevel=True, behavior=None, attrs=None)#
arrays – Array-like data (anything
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.
mergebool (bool) – If True, boolean and numeric data can be combined into the same buffer, losing information about False vs
0and True vs
1; otherwise, they are kept in separate buffers with distinct types (using an
attrs (None or dict) – Custom attributes for the output array, if high-level.
Returns an array with
arrays concatenated. For
axis=0, this means that
one whole array follows another. For
axis=1, it means that the
must have the same lengths and nested lists are each concatenated,
element for element, and similarly for deeper levels.
