torch.cos# torch.cos(input, *, out=None) → Tensor# Returns a new tensor with the cosine of the elements of input. outi=cos(inputi)\text{out}_{i} = \cos(\text{input}_{i}) outi=cos(inputi) Parameters input (Tensor) – the input tensor. Keyword Arguments out (Tensor, optional) – the output tensor. Example: >>> a = torch.randn(4) >>> a tensor([ 1.4309, 1.2706, -0.8562, 0.9796]) >>> torch.cos(a) tensor([ 0.1395, 0.2957, 0.6553, 0.5574])
