mindspore.ops.csr_cos(x: CSRTensor)[source]

Computes cosine of input element-wise.

\[out_i = \cos(x_i)\]

Warning

Currently support data types float16 and float32. If use float64, there may be a problem of missing precision.

Parameters

x (CSRTensor) – Input CSRTensor.

Returns

CSRTensor, has the same shape and dtype as x.

Raises

  • TypeError – If x is not a CSRTensor.

  • TypeError – If dtype of x is not float16, float32 or float64, complex64, complex128.

Supported Platforms:

Ascend GPU CPU

Examples

>>> from mindspore import dtype as mstype
>>> from mindspore import Tensor, ops, CSRTensor
>>> indptr = Tensor([0, 1, 2, 2], dtype=mstype.int32)
>>> indices = Tensor([3, 0], dtype=mstype.int32)
>>> values = Tensor([-1, 2], dtype=mstype.float32)
>>> shape = (3, 4)
>>> x = CSRTensor(indptr, indices, values, shape)
>>> output = ops.csr_cos(x)
>>> print(output.values)
