**Short description**: *Atan* performs element-wise inverse tangent (arctangent) operation with given tensor.
**Attributes**:
No attributes available.
**Inputs**
* **1**: An tensor of type *T*. **Required.**
**Outputs**
* **1**: The result of element-wise atan operation. A tensor of type *T*.
**Types**
* *T*: any numeric type.
*atan* does the following with the input tensor *a*:
**Detailed description**: Operation takes one input tensor and performs the element-wise inverse tangent function on a given input tensor, based on the following mathematical formula:
\f[
a_{i} = atan(a_{i})
\f]
**Examples**
**Attributes**: *Atan* operation has no attributes.
*Example 1*
**Inputs**
* **1**: A tensor of type *T* and arbitrary shape. **Required.**
**Outputs**
* **1**: The result of element-wise *Atan* applied to the input tensor. A tensor of type *T* and same shape as the input tensor.
**Types**
* *T*: any supported numeric type.
