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 NodeTypeInfo &get_type_info() const

Returns the NodeTypeInfo for the node’s class. During transition to type_info, returns a dummy type_info for Node if the class has not been updated yet.

Cosh()

Constructs a hyperbolic cosine operation.

Cosh(const Output<Node> &arg)

Constructs a hyperbolic cosine operation.

Parameters
  • arg: Node that produces the input tensor.
