megengine.functional.neg¶

Element-wise negation.

Computes the numerical negative of each element \(x_i\) (i.e., \(y_i = -x_i\) ) of the input tensor \(x\).

Parameters: x (Tensor) – input tensor. Should have a numeric data type.
Return type: Tensor
Returns: A tensor containing the evaluated result for each element in \(x\). The returned tensor must have a data type determined by Type promotion rules.

Note

The unary - operator can be used as a shorthand for neg on tensors.

Examples

>>> x = Tensor([1, -1])
>>> F.neg(x)
Tensor([-1  1], dtype=int32, device=xpux:0)
