**Versioned name**: *Cosh-1*

**Category**: *Arithmetic unary*

**Short description**: *Cosh* performs element-wise hyperbolic cosine operation on a given input tensor.

**Detailed description**: *Cosh* performs element-wise hyperbolic cosine (cosh) operation on a given input tensor, based on the following mathematical formula:

.. math::
   
   a_{i} = cosh(a_{i})

**Attributes**: *Cosh* operation has no attributes.

**Inputs**

* **1**: A tensor of type *T* and arbitrary shape. **Required.**

**Outputs**

* **1**: The result of element-wise *Cosh* operation. A tensor of type *T* and the same shape as the input tensor.

**Types**

* *T*: any numeric type.

**Example**

.. code-block:: cpp
   
   <layer ... type="Cosh">
       <input>
           <port id="0">
               <dim>256</dim>
               <dim>56</dim>
           </port>
       </input>
       <output>
           <port id="1">
               <dim>256</dim>
               <dim>56</dim>
           </port>
       </output>
   </layer>
