dpnp.rollaxis

dpnp.rollaxis(x1, axis, start=0)[source]

Roll the specified axis backwards, until it lies in a given position.

For full documentation refer to numpy.rollaxis.

Limitations

Input array is supported as dpnp.ndarray. Parameter axis is supported as integer only. Parameter start is limited by -a.ndim <= start <= a.ndim. Otherwise the function will be executed sequentially on CPU. Input array data types are limited by supported DPNP Data types.

dpnp.roll: Roll the elements of an array by a number of positions along a given axis.

Examples

>>> import dpnp as np
>>> a = np.ones((3,4,5,6))
>>> np.rollaxis(a, 3, 1).shape
(3, 6, 4, 5)
>>> np.rollaxis(a, 2).shape
(5, 3, 4, 6)
>>> np.rollaxis(a, 1, 4).shape
(3, 5, 6, 4)
