# scipy.special.cbrt

scipy.special.cbrt(x, out=None) = <ufunc 'cbrt'>

  Element-wise cube root of x.

  Parameters:
    x array_like

      x must contain real numbers.

    out ndarray, optional

      Optional output array for the function values

  Returns:
    scalar or ndarray

      The cube root of each value in x.

  Notes

  Array API Standard Support

  `cbrt` has experimental support for Python Array API Standard compatible backends in addition to NumPy. Please consider testing these features by setting an environment variable `SCIPY_ARRAY_API=1` and providing CuPy, PyTorch, JAX, or Dask arrays as array arguments. The following combinations of backend and device (or other capability) are supported.

  Library | CPU | GPU
  --- | --- | ---
  NumPy | ✅ | n/a
  CuPy | n/a | ✅
  PyTorch | ✅ | ⛔
  JAX | ✅ | ⛔
  Dask | ✅ | n/a

  See Support for the array API standard for more information.

  Examples

      >>> from scipy.special import cbrt

      >>> cbrt(8)
      2.0
      >>> cbrt([-8, -3, 0.125, 1.331])
      array([-2.        , -1.44224957,  0.5       ,  1.1       ])
