mindspore.Tensor.atanh

Tensor.atanh(self) → Tensor

Computes inverse hyperbolic tangent of self element-wise.

\[out_i = \tanh^{-1}(input_{i})\]

Returns: Tensor, has the same shape as self. The dtype of output is float32 when dtype of self is in [bool, int8, uint8, int16, int32, int64]. Otherwise output has the same dtype as self.
Raises: TypeError – If self is not a Tensor.

Supported Platforms:: Ascend GPU CPU

Examples

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