Join a sequence of arrays along a new axis.

LAX-backend implementation of numpy.stack().

Original docstring below.

The axis parameter specifies the index of the new axis in the dimensions of the result. For example, if axis=0 it will be the first dimension and if axis=-1 it will be the last dimension.

Added in version 1.10.0.

Parameters:

  • arrays (sequence of array_like) – Each array must have the same shape.

  • axis (int, optional) – The axis in the result array along which the input arrays are stacked.

  • dtype (str or dtype) – If provided, the destination array will have this dtype. Cannot be provided together with out.

  • out (None)
