get_diagonal()

template<typename ExecSpace , typename Matrix , typename Vector >

void Morpheus::get_diagonal	(	const Matrix &	A,
		Vector &	diagonal
	)

Gets the main diagonal of the matrix and places it in a vector.

Template Parameters

ExecSpace	Execution space to run the algorithm
Matrix	The type of the matrix container
Vector	The type of the extracted diagonal

Parameters

A	The matrix to extract the diagonal from
diagonal	The main matrix diagonal represented as a vector

set_value()

template<typename ExecSpace , typename Matrix , typename SizeType , typename ValueType >

void Morpheus::set_value	(	Matrix &	A,
		SizeType	row,
		SizeType	col,
		ValueType	value
	)

Set a single entry into a matrix.

Template Parameters

ExecSpace	Execution space to run the algorithm
Matrix	The type of the matrix container
IndexType	The type of the indices of the matrix
ValueType	The type of the values of the matrix

Parameters

A	The matrix to update
row	The row location of the entry
col	The column location of the entry
value	The value to insert

set_values()

template<typename ExecSpace , typename Matrix , typename IndexVector , typename ValueVector >

void Morpheus::set_values	(	Matrix &	A,
		typename IndexVector::value_type	m,
		const IndexVector	idxm,
		typename IndexVector::value_type	n,
		const IndexVector	idxn,
		ValueVector	values
	)

Inserts or adds a block of values into a matrix.

Template Parameters

ExecSpace	Execution space to run the algorithm
Matrix	The type of the matrix container
IndexVector	The type of the container holding the indices
ValueVector	The type of the container holding the values

Parameters

A	The matrix to update
m	The number of rows
idxm	Row global indices
n	The number of columns
idxn	Column global indices
values	A logically two-dimensional array of values

transpose()

template<typename ExecSpace , typename Matrix , typename TransposeMatrix >

void Morpheus::transpose	(	const Matrix &	A,
		TransposeMatrix &	At
	)

Computes the transpose of the given matrix.

Template Parameters

ExecSpace	Execution space to run the algorithm
Matrix	The type of the matrix container
TransposeMatrix	The type of the transposed matrix container

Parameters

A	The matrix to transpose
B	The transposed matrix

update_diagonal()

template<typename ExecSpace , typename Matrix , typename Vector >

void Morpheus::update_diagonal	(	Matrix &	A,
		const Vector &	diagonal
	)

Updates the main diagonal of the matrix with contents of the diagonal vector.

Template Parameters

ExecSpace	Execution space to run the algorithm
Matrix	The type of the matrix container
Vector	The type of the vector representing the diagonal

Parameters

A	The matrix to update the diagonal for
diagonal	The matrix diagonal represented as a vector

Note

The sparsity pattern of the matrix remains unchanged i.e it only updates the non-zero elements on the main diagonal.
