numpy.cbrt¶

numpy.
cbrt
(x, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj]) = <ufunc 'cbrt'>¶ Return the cuberoot of an array, elementwise.
New in version 1.10.0.
Parameters: x : array_like
The values whose cuberoots are required.
out : ndarray, None, or tuple of ndarray and None, optional
A location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshlyallocated array is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs.
where : array_like, optional
Values of True indicate to calculate the ufunc at that position, values of False indicate to leave the value in the output alone.
**kwargs
For other keywordonly arguments, see the ufunc docs.
Returns: y : ndarray
An array of the same shape as x, containing the cube cuberoot of each element in x. If out was provided, y is a reference to it.
Examples
>>> np.cbrt([1,8,27]) array([ 1., 2., 3.])
