mindspore.ops.acos

mindspore.ops.acos(input)[source]

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 and dtype as input.

Raises

TypeError – If input is not a Tensor.
TypeError – If dtype of input is not float16, float32 or float64, complex64, complex128.

Supported Platforms:: Ascend GPU CPU

Examples

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