mindspore.ops.acosh

mindspore.ops.acosh(input)[source]

Computes inverse hyperbolic cosine of the inputs element-wise.

\[out_i = \cosh^{-1}(input_i)\]

Warning

Given an input tensor input, the function computes inverse hyperbolic cosine of every element. Input range is [1, inf].

Parameters: input (Tensor) – The input tensor of inverse hyperbolic cosine function.
Returns: Tensor, has the same shape and type as input.
Raises: TypeError – If input is not a Tensor.

Supported Platforms:: Ascend GPU CPU

Examples

>>> import mindspore
>>> import numpy as np
>>> from mindspore import Tensor, ops
>>> x = Tensor(np.array([1.0, 1.5, 3.0, 100.0]), mindspore.float32)
>>> output = ops.acosh(x)
>>> print(output)
