mindspore.mint.acos

mindspore.mint.acos(input)[source]

Computes arccosine of input tensors element-wise.

o u t_{i} = \cos^{- 1} (i n p u t_{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:: Ascend

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)
