Atanh

torch_atanh(self)

Arguments

self

(Tensor) the input tensor.

Note

The domain of the inverse hyperbolic tangent is (-1, 1) and values outside this range will be mapped to NaN, except for the values 1 and -1 for which the output is mapped to +/-INF respectively.

$$ \mbox{out}_{i} = \tanh^{-1}(\mbox{input}_{i}) $$

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

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

Examples

if (torch_is_installed()) { a = torch_randn(c(4))$uniform_(-1, 1) a torch_atanh(a) }
