mindspore.mint.cos

mindspore.mint.cos(input)[source]

Computes cosine of input element-wise.

\[out_i = \cos(x_i)\]

Warning

Using float64 may cause a problem of missing precision.

Parameters

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

Returns

Tensor, has the same shape as the 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 the input.

Raises

TypeError – If input is not a Tensor.
TypeError –
- Ascend: If dtype of input is not bool, int8, uint8, int16, int32, int64, float16, float32, float64, complex64, complex128.

Supported Platforms:: Ascend

Examples

>>> import mindspore
>>> import numpy as np
>>> from mindspore import Tensor, mint
>>> input = Tensor(np.array([0.24, 0.83, 0.31, 0.09]), mindspore.float32)
>>> output = mint.cos(input)
>>> print(output)
[0.971338 0.6748758 0.95233357 0.9959527]
