# Cosh¶

Cosh  //  Elementwise hyperbolic cosine operation


## Description¶

Produces a tensor of the same element type and shape as arg, where the value at each coordinate of output is the hyperbolic cosine of the value at the corresponding coordinate of arg.

### Inputs¶

Name Element Type Shape
arg Any Any

### Outputs¶

Name Element Type Shape
output Same as arg Same as arg

## Mathematical Definition¶

$\mathtt{output}_{i_0, \ldots, i_{n-1}} = \cosh(\mathtt{arg}_{i_0, \ldots, i_{n-1}})$

## Backprop¶

$\overline{\mathtt{arg}} \leftarrow \Delta\ \sinh(\mathtt{arg})$

## C++ Interface¶

class Cosh : public ngraph::op::util::UnaryElementwiseArithmetic

Elementwise hyperbolic cosine (cosh) operation.

Public Functions

const std::string &description() const

Get the string name for the type of the node, such as Add or Multiply. The class name, must not contain spaces as it is used for codegen.

Return
A const reference to the node’s type name

Cosh()

Constructs a hyperbolic cosine operation.

Cosh(const Output<Node> &arg)

Constructs a hyperbolic cosine operation.

Parameters
• arg: Node that produces the input tensor.
