mindspore.Tensor.cos

Tensor.cos() → Tensor

Computes cosine of self element-wise.

$$ou{t}_i=\cos (sel{f}_i)$$

Warning

Using float64 may cause a problem of missing precision.

Returns

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

Raises

• TypeError – If self is not a Tensor.

• TypeError –

  • CPU/GPU: If dtype of self is not float16, float32 or float64, complex64, complex128.

  • Ascend: If dtype of self is not bool, int8, uint8, int16, int32, int64, float16, float32, float64, complex64, complex128.

Supported Platforms:

Ascend GPU CPU

Examples

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