mindspore.ops.coo_cos

mindspore.ops.coo_cos(x: COOTensor)[source]

Computes cosine of input element-wise.

\[out_i = cos(x_i)\]

Warning

If use Float64, there may be a problem of missing precision.

Parameters

x (COOTensor) – Input COOTensor.

Returns

COOTensor, has the same shape and dtype as x.

Raises

TypeError – If x is not a COOTensor.
TypeError – If dtype of x is not float16, float32 or float64, complex64,

complex128.

Supported Platforms:: Ascend GPU CPU

Examples

>>> indices = Tensor([[0, 1], [1, 2]], dtype=mstype.int64)
>>> values = Tensor([-1, 2], dtype=mstype.float32)
>>> shape = (3, 4)
>>> x = COOTensor(indices, values, shape)
>>> output = ops.coo_cos(x)
>>> print(output.values)
