|
**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:
|
|
|
|
\f[ a_{i} = atanh(a_{i}) \f]
|
|
|
|
Signed Intragral type put:
|
|
|
|
\f[ a_{i} = (i <= -1) ? std::numeric_limits<T>::min() : (i >= 1) ? std::numeric_limits<T>::max() : atanh(a_{i}) \f]
|
|
|
|
Unsigned Intragral type put:
|
|
|
|
\f[ a_{i} = (i > 0) ? std::numeric_limits<T>::max() : atanh(a_{i}) \f]
|
|
|
|
|
|
**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.
|
