mindspore.ops.coo_neg

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

Returns a COOTensor with coo_negative values of the input COOTensor element-wise.

\[out_{i} = - x_{i}\]

Parameters: x (COOTensor) – The input COOTensor with a dtype of Number.
Returns: COOTensor, has the same shape and dtype as input.
Raises: TypeError – If x is not a COOTensor.

Supported Platforms:: Ascend GPU CPU

Examples

>>> from mindspore import dtype as mstype
>>> from mindspore import Tensor, ops, COOTensor
>>> 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_neg(x)
>>> print(output.values)
