Detailed Description

Represents the outer product operation between two vectors.

The outer product of two vectors with shapes (n) and (m) results in a matrix of shape (n, m). Currently, only vectors are supported — tensors with rank greater than 1 are not supported, but this may be extended in the future.

Member Function Documentation

forward()

void tannic::transformation::Outer::forward	(	Tensor const &	first,
		Tensor const &	second,
		Tensor &	result
	)		const

promote()

static constexpr type tannic::transformation::Outer::promote ( type  first, type  second  )

inlinestaticconstexpr

Type promotion for the outer product operation.

Promotes two operand types to the higher precision type.

Parameters

first	Type of the first operand (left)
second	Type of the second operand (right)

Returns

Promoted type for outer product computation

transform()

static constexpr Shape tannic::transformation::Outer::transform ( Shape const &  first, Shape const &  second  )

inlinestaticconstexpr

Computes output shape for the outer product of two vectors.

Parameters

first	Shape of the first tensor
second	Shape of the second tensor

Returns

Shape of the resulting outer product tensor

Exceptions

assertion

error if either input tensor is not rank 1 for now outer product only support vectors and not general tensors but this may change in the future.

The outer product of two vectors with shapes (n) and (m) produces a matrix of shape (n, m). Outer product is not defined here for tensors with rank > 1.
