mindspore.mint.acos

mindspore.mint.acos(input)

Computes arccosine of input tensors element-wise.

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

Parameters

input (Tensor) – The shape of tensor is \((N,*)\), where \(*\) means any number of additional dimensions.

Returns

Tensor, has the same shape as input. The dtype of output is float32 when dtype of input is in [bool, int8, uint8, int16, int32, int64]. Otherwise output has the same dtype as input.

Raises

TypeError – If input is not a Tensor.

Supported Platforms:

Examples

>>> import mindspore
>>> import numpy as np
>>> from mindspore import Tensor, mint
>>> input = Tensor(np.array([0.74, 0.04, 0.30, 0.56]), mindspore.float32)
>>> output = mint.acos(input)
>>> print(output)
