cunumeric.hstack#

cunumeric.hstack(tup: Sequence[ndarray]) → ndarray#

Stack arrays in sequence horizontally (column wise).

This is equivalent to concatenation along the second axis, except for 1-D arrays where it concatenates along the first axis. Rebuilds arrays divided by hsplit.

This function makes most sense for arrays with up to 3 dimensions. For instance, for pixel-data with a height (first axis), width (second axis), and r/g/b channels (third axis). The functions concatenate, stack and block provide more general stacking and concatenation operations.

Parameters:: tup (Sequence[ndarray]) – The arrays must have the same shape along all but the second axis, except 1-D arrays which can be any length.
Returns:: stacked – The array formed by stacking the given arrays.
Return type:: ndarray
