torch.atan# torch.atan(input: Tensor, *, out: Optional[Tensor]) → Tensor# Returns a new tensor with the arctangent of the elements of input. outi=tan−1(inputi) ext{out}_{i} = an^{-1}( ext{input}_{i}) outi=tan−1(inputi) 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])
