Multiply¶

Multiply  //  Elementwise multiply operation


Description¶

Produces tensor of the same element type and shape as the two inputs, where the value at each coordinate of output is the product of the values at the corresponding input coordinates.

Inputs¶

Name Element Type Shape
arg0 any any
arg1 same as arg0 same as arg0

Outputs¶

Name Element Type Shape
output same as arg0 same as arg0

Mathematical Definition¶

$\mathtt{output}_{i_0, \ldots, i_{n-1}} = \mathtt{arg0}_{i_0, \ldots, i_{n-1}} \mathtt{arg1}_{i_0, \ldots, i_{n-1}}$

Backprop¶

$\begin{split}\overline{\mathtt{arg0}} &\leftarrow \Delta\ \mathtt{arg1}\\ \overline{\mathtt{arg1}} &\leftarrow \Delta\ \mathtt{arg0}\end{split}$

C++ Interface¶

class Multiply : public ngraph::op::util::BinaryElementwiseArithmetic

Elementwise multiplication operation.

Public Functions

Multiply(const std::shared_ptr<Node> &arg0, const std::shared_ptr<Node> &arg1)

Constructs a multiplication operation.

Parameters
• arg0: Node that produces the first input tensor.
• arg1: Node that produces the second input tensor.
