Acosh
Note
The domain of the inverse hyperbolic cosine is [1, inf) and values outside this range
will be mapped to NaN, except for + INF for which the output is mapped to + INF.
$$ \mbox{out}_{i} = \cosh^{-1}(\mbox{input}_{i}) $$
acosh(input, *, out=None) -> Tensor
Returns a new tensor with the inverse hyperbolic cosine of the elements of input.
Examples
if (torch_is_installed()) {
a <- torch_randn(c(4))$uniform_(1, 2)
a
torch_acosh(a)
