torch.atan(input: Tensor, *, out: Optional[Tensor]) → Tensor¶

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

outi=tan⁡−1(inputi)\text{out}_{i} = \tan^{-1}(\text{input}_{i})

Parameters

input (Tensor) – the input tensor.

Keyword Arguments

out (Tensor, optional) – the output tensor.

Example:

a = torch.randn(4) a tensor([ 0.2341, 0.2539, -0.6256, -0.6448]) torch.atan(a) tensor([ 0.2299, 0.2487, -0.5591, -0.5727])
