class saiunit.math.roll(a, shift, axis=None, **kwargs)#

Roll quantity or array elements along a given axis.

Parameters:

  • a (Array | saiunit.Quantity) – Input array.

  • shift (int | Tuple[int, ...]) – The number of places by which elements are shifted. If a tuple, then axis must be a tuple of the same size, and each of the given axes is shifted by the corresponding number. If an int while axis is a tuple of ints, then the same value is used for all given axes.

  • axis (int | Tuple[int, ...] | None) – Axis or axes along which elements are shifted. By default, the array is flattened before shifting, after which the original shape is restored.

Returns:

res – Output array, with the same shape as a.

Return type:

Array | saiunit.Quantity

Examples

>>> import saiunit as u
>>> a = [1, 2, 3] * u.second
>>> u.math.roll(a, 1)
