torch.cosh — PyTorch 2.7 documentation (original) (raw)

torch.cosh(input, *, out=None) → Tensor¶

Returns a new tensor with the hyperbolic cosine of the elements ofinput.

outi=cosh⁡(inputi)\text{out}_{i} = \cosh(\text{input}_{i})

Parameters

input (Tensor) – the input tensor.

Keyword Arguments

out (Tensor, optional) – the output tensor.

Example:

a = torch.randn(4) a tensor([ 0.1632, 1.1835, -0.6979, -0.7325]) torch.cosh(a) tensor([ 1.0133, 1.7860, 1.2536, 1.2805])

Note

When input is on the CPU, the implementation of torch.cosh may use the Sleef library, which rounds very large results to infinity or negative infinity. See here for details.
