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 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.

Cos()

Constructs a cosine operation.

Cos(const Output<Node> &arg)

Constructs a cosine operation.

Parameters
• arg: Node that produces the input tensor.
