Detailed Description

template<class T, class Prop, class Storage, class Allocator = typename SeldonDefaultAllocator<Storage, T>::allocator>
class Seldon::Matrix_SymSparse< T, Prop, Storage, Allocator >

Symmetric sparse-matrix class.

Symmetric sparse matrices are defined by: (1) the number of rows and columns; (2) the number of non-zero entries; (3) an array 'ptr_' of start indices (i.e. indices of the first element of each row or column, depending on the storage); (4) an array 'ind_' of column or row indices of each non-zero entry; (5) values of non-zero entries.

: Only values of the upper part are stored.

		int	j
	)

inline

Constructor.

Builds a i by j sparse matrix.

Parameters

i	number of rows.
j	number of columns.

Note: 'j' is assumed to be equal to 'i' and is therefore discarded.

Definition at line 57 of file Matrix_SymSparseInline.cxx.

Constructor.

Builds a sparse matrix of size i x j , with nz non-zero (stored) elements.

Parameters

i	number of rows.
j	number of columns.
nz	number of non-zero elements that are stored.

Note: Matrix values are not initialized. Indices of non-zero entries are not initialized either.; 'j' is assumed to be equal to 'i' and is therefore discarded.

void Seldon::Matrix_SymSparse< T, Prop, Storage, Allocator >::SetEntry	(	int	i,
		int	j,
		const T &	val
	)

inline

Sets an element (i, j) to a value.

This function sets val to the element (i, j)

Parameters

[in]	i	row index.
[in]	j	column index.
[in]	val	A(i, j) = val

Definition at line 255 of file Matrix_SymSparseInline.cxx.

◆ SetIdentity()

template<class T , class Prop , class Storage , class Allocator >

void Seldon::Matrix_SymSparse< T, Prop, Storage, Allocator >::SetIdentity

Sets the matrix to identity.

This method fills the diagonal of the matrix with ones.

◆ Val() [1/2]

template<class T , class Prop , class Storage , class Allocator >

Matrix_SymSparse< T, Prop, Storage, Allocator >::value_type & Seldon::Matrix_SymSparse< T, Prop, Storage, Allocator >::Val	(	int	i,
		int	j
	)

Access method.

Returns the value of element (i, j) if it can be returned as a reference.

Parameters

[in]	i	row index.
[in]	j	column index.

Returns: Element (i, j) of the matrix.

Exceptions

WrongArgument No reference can be returned because the element is a zero entry (not stored in the matrix).

Definition at line 936 of file Matrix_SymSparse.cxx.

◆ Val() [2/2]

template<class T , class Prop , class Storage , class Allocator >

const Matrix_SymSparse< T, Prop, Storage, Allocator >::value_type & Seldon::Matrix_SymSparse< T, Prop, Storage, Allocator >::Val	(	int	i,
		int	j
	)		const

Access method.

Returns the value of element (i, j) if it can be returned as a reference.

Parameters

[in]	i	row index.
[in]	j	column index.

Returns: Element (i, j) of the matrix.

Exceptions

WrongArgument No reference can be returned because the element is a zero entry (not stored in the matrix).

◆ Write() [1/2]

template<class T , class Prop , class Storage , class Allocator >

void Seldon::Matrix_SymSparse< T, Prop, Storage, Allocator >::Write ( ostream & FileStream ) const

Writes the matrix to an output stream.

Stores the matrix in an output stream in binary format.

Parameters

FileStream output stream.

Definition at line 1248 of file Matrix_SymSparse.cxx.

◆ Write() [2/2]

template<class T , class Prop , class Storage , class Allocator >

void Seldon::Matrix_SymSparse< T, Prop, Storage, Allocator >::Write ( string FileName ) const

Writes the matrix in a file.

Stores the matrix in a file in binary format.

Parameters

FileName output file name.

Definition at line 1223 of file Matrix_SymSparse.cxx.

◆ WriteText() [1/2]

template<class T , class Prop , class Storage , class Allocator >

void Seldon::Matrix_SymSparse< T, Prop, Storage, Allocator >::WriteText	(	ostream &	FileStream,
		bool	cplx = `false`
	)		const

Writes the matrix to an output stream.

Stores the matrix in a file in ascii format. The entries are written in coordinate format (row index, column index, value). Row and column indexes start at 1.

Parameters

FileStream	output file name.
cplx	if true the real part and imaginary part are given in two separate columns, otherwise the complex values are written (a,b)

Definition at line 1316 of file Matrix_SymSparse.cxx.

◆ WriteText() [2/2]

template<class T , class Prop , class Storage , class Allocator >

void Seldon::Matrix_SymSparse< T, Prop, Storage, Allocator >::WriteText	(	string	FileName,
		bool	cplx = `false`
	)		const

Writes the matrix in a file.

Stores the matrix in a file in ascii format. The entries are written in coordinate format (row index, column index, value). Row and column indexes start at 1.

Parameters

FileName	output file name.
cplx	if true the real part and imaginary part are written in two separate columns, otherwise the complex values are written (a,b)

Definition at line 1284 of file Matrix_SymSparse.cxx.

◆ Zero()

template<class T , class Prop , class Storage , class Allocator >

void Seldon::Matrix_SymSparse< T, Prop, Storage, Allocator >::Zero

Resets all non-zero entries to 0-value.

The sparsity pattern remains unchanged.
