Atan

Atan // Elementwise atan operation

Description

Produces a tensor of the same element type and shape as arg, where the value at each coordinate of output is the inverse tangent 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

\[\mathtt{output}_{i_0, \ldots, i_{n-1}} = \tan^{-1}(\mathtt{arg}_{i_0, \ldots, i_{n-1}})\]

Backprop

\[\overline{\mathtt{arg}} \leftarrow \frac{\Delta}{1+\mathtt{arg}^2}\]

C++ Interface

class Atan : public ngraph::op::util::UnaryElementwiseArithmetic

Elementwise inverse tangent (arctan) operation.

Public Functions

Atan(const std::shared_ptr<Node> &arg)

Constructs an arctan operation.

Output

[d1, ...]
Parameters
  • arg: Node that produces the input tensor.[d1, ...]
