Atanh

Versioned name: Atanh-3

Category: Arithmetic unary

Short description: Atanh performs element-wise hyperbolic inverse tangent (arctangenth) operation with a given tensor.

Detailed description: Atanh performs element-wise hyperbolic inverse tangent (arctangenth) operation on a given input tensor, based on the following mathematical formula:

Float type input:

\[a_{i} = atanh(a_{i})\]

Signed Intragral type put:

\[a_{i} = (i <= -1) ? std::numeric_limits<T>::min() : (i >= 1) ? std::numeric_limits<T>::max() : atanh(a_{i})\]

Unsigned Intragral type put:

\[a_{i} = (i > 0) ? std::numeric_limits<T>::max() : atanh(a_{i})\]

Attributes: Atanh operation has no attributes.

Inputs

• 1: A tensor of type T. Required.

Outputs

• 1: The result of element-wise atanh operation applied to the input tensor. A tensor of type T and the same shape as input tensor.

Types

• T: any supported numeric type.
