Cos¶

Cos  //  Elementwise 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 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¶

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

Backprop¶

$\overline{\mathtt{arg}} \leftarrow -\Delta\ \sin(\mathtt{arg})$

C++ Interface¶

class Cos : public ngraph::op::util::UnaryElementwiseArithmetic

Elementwise cosine 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

Cos()

Constructs a cosine operation.

Cos(const Output<Node> &arg)

Constructs a cosine operation.

Parameters
• arg: Node that produces the input tensor.
