torch_acosh {torch}

Acosh

Description

Acosh

Usage

torch_acosh(self)

Arguments

self

(Tensor) the input tensor.

acosh(input, *, out=None) -> Tensor

Returns a new tensor with the inverse hyperbolic cosine of the elements of input.

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})

Examples

if (torch_is_installed()) {

a <- torch_randn(c(4))$uniform_(1, 2)
a
torch_acosh(a)
}
