hstack#

ivy.hstack(arrays, /, *, out=None)[source]#

Stack arrays in sequence horizotally (column wise).

Parameters:: arrays (Sequence[Array]) – Sequence of arrays to be stacked.
Return type:: Array
Returns:: ret – The array formed by stacking the given arrays.

Examples

>>> x = ivy.array([1, 2, 3])
>>> y = ivy.array([2, 3, 4])
>>> ivy.hstack((x, y))
ivy.array([1, 2, 3, 2, 3, 4])
>>> x = ivy.array([1, 2, 3])
>>> y = ivy.array([0, 0, 0])
>>> ivy.hstack((x, y, x))
ivy.array([1, 2, 3, 0, 0, 0, 1, 2, 3])
>>> y = [ivy.array([[5, 6]]), ivy.array([[7, 8]])]
>>> print(ivy.hstack(y))
ivy.array([[5, 6, 7, 8]])

Array.hstack(self, arrays, /, *, out=None)[source]#

ivy.Array instance method variant of ivy.hstack. This method simply wraps the function, and so the docstring for ivy.hstack also applies to this method with minimal changes.

Return type:: Array

Examples

>>> x = ivy.array([[1, 2]])
>>> y = [ivy.array([[5, 6]]), ivy.array([[7, 8]])]
>>> print(x.vstack(y))
ivy.array([1, 2, 5, 6, 7, 8])

Container.hstack(self, /, xs, *, key_chains=None, to_apply=True, prune_unapplied=False, map_sequences=False, out=None)[source]#

ivy.Container instance method variant of ivy.hstack. This method simply wraps the function, and so the docstring for ivy.hstack also applies to this method with minimal changes.

Return type:: Container

Examples

>>> x = ivy.Container(a=ivy.array([[0, 1], [2,3]]), b=ivy.array([[4, 5]]))
>>> y = ivy.Container(a=ivy.array([[3, 2], [1,0]]), b=ivy.array([[1, 0]]))
>>> z = x.hstack([y])
>>> print(z)
{
    a: ivy.array([[0, 1, 3, 2],
                  [2, 3, 1, 0]]),
    b: ivy.array([[4, 5, 1, 0]])
}
