Detailed Description

A calculator for all matrices that are the row selection of a diagonal matrix. The structure of the matrix (position of non-zero elements) is assumed to be constant.

Constructor & Destructor Documentation

◆ DiagonalCalculator() [1/2]

tvm::hint::internal::DiagonalCalculator::DiagonalCalculator	(	Eigen::DenseIndex	first = `0`,
		Eigen::DenseIndex	size = `-1`
	)

Continuous rows of a diagonal matrix starting at row first of this matrix and finishing at row first + size (not included). If size = -1, finishes at the last row.

◆ DiagonalCalculator() [2/2]

tvm::hint::internal::DiagonalCalculator::DiagonalCalculator	(	const std::vector< Eigen::DenseIndex > &	nnzRows,
		const std::vector< Eigen::DenseIndex > &	zeroRows = `{}`
	)

Non-continuous rows of a diagonal matrix

Parameters

nnzRows	indices of the rows with a non-zero element.
zeroRows	indices of the rows (if any) with only zero

Examples: Knowing that it describes a matrix with 6 columns, nnzRows = {0,2,3}, zeroRows = {} corresponds to the shape x 0 0 0 0 0 0 0 x 0 0 0 0 0 0 x 0 0

while nnzRows = {0,2,3}, zeroRows = {1,4} corresponds to x 0 0 0 0 0 0 0 0 0 0 0 0 0 x 0 0 0 0 0 0 x 0 0 0 0 0 0 0 0
