mindspore.ops.atanh

mindspore.ops.atanh(input)[source]

Computes inverse hyperbolic tangent of the input element-wise.

o u t_{i} = \tanh^{- 1} (i n p u t_{i})

Parameters

input (Tensor) – The shape of tensor is $(N, *)$ where $*$ means, any number of additional dimensions. The data type should be one of the following types: float16, float32.

Returns

A Tensor, has the same type as the input.

Raises

TypeError – If input is not a Tensor.
TypeError – If dtype of input is not float16 or float32.

Supported Platforms:: Ascend GPU CPU

Examples

>>> import mindspore
>>> import numpy as np
>>> from mindspore import Tensor, ops
>>> input = Tensor(np.array([0, -0.5]), mindspore.float32)
>>> output = ops.atanh(input)
>>> print(output)
[ 0.         -0.54930615]
