torch.neg

torch.neg(input, *, out=None) → Tensor

Returns a new tensor with the negative of the elements of input.

$$\text{out} = -1 \times \text{input}$$

Parameters:

input (Tensor) – the input tensor.

Keyword Arguments:

out (Tensor, optional) – the output tensor.

Example:

>>> a = torch.randn(5)
>>> a
tensor([ 0.0090, -0.2262, -0.0682, -0.2866,  0.3940])
>>> torch.neg(a)
tensor([-0.0090,  0.2262,  0.0682,  0.2866, -0.3940])
