cos¶

dragon.vm.torch.cos(
  input,
  out=None
)[source]¶

Compute the cos of input.

\[\text{out} = \cos(\text{input}) \]

Examples:

x = torch.tensor([0., math.pi])
print(torch.cos(x))  # [1., -1.]

Parameters:

• input (dragon.vm.torch.Tensor) – The input tensor.
• out (dragon.vm.torch.Tensor, optional) – The output tensor.

Returns:

dragon.vm.torch.Tensor – The output tensor.
