Detailed Description

template<class ValueType>
class GIMLI::SparseMatrix< ValueType >

Sparse matrix in compressed row storage (CRS) form.

Sparse matrix in compressed row storage (CRS) form. IF you need native CCS format you need to transpose CRS Symmetry type: 0 = nonsymmetric, -1 symmetric lower part, 1 symmetric upper part.

Constructor & Destructor Documentation

SparseMatrix() [1/3]

template<class ValueType >

GIMLI::SparseMatrix< ValueType >::SparseMatrix ( )

inline

Default constructor. Builds invalid sparse matrix

SparseMatrix() [2/3]

template<class ValueType >

GIMLI::SparseMatrix< ValueType >::SparseMatrix ( const SparseMatrix< ValueType > &  S )

inline

Copy constructor.

References GIMLI::SparseMapMatrix< ValueType, IndexType >::stype().

SparseMatrix() [3/3]

template<class ValueType >

GIMLI::SparseMatrix< ValueType >::SparseMatrix ( const SparseMapMatrix< ValueType, Index > &  S )

inline

Copy constructor.

Member Function Documentation

copy_()

template<typename ValueType >

void GIMLI::SparseMatrix< ValueType >::copy_

(

const SparseMapMatrix< double, Index > &

S

)

SparseMatrix specialized type traits in sparsematrix.cpp

getVal()

template<class ValueType >

ValueType GIMLI::SparseMatrix< ValueType >::getVal ( int  i, int  j, bool  warn = true  ) const

inline

Get matrix value at i,j. If i and j is not part of the matrix sparsity pattern return 0 and print a warning. This warning can be disabled by setting warn to false.

mult()

template<class ValueType >

virtual Vector< ValueType > GIMLI::SparseMatrix< ValueType >::mult ( const Vector< ValueType > &  a ) const

inlinevirtual

Return this * a

operator=()

template<class ValueType >

SparseMatrix< ValueType >& GIMLI::SparseMatrix< ValueType >::operator= ( const SparseMatrix< ValueType > &  S )

inline

Copy assignment operator.

stype()

template<class ValueType >

int GIMLI::SparseMatrix< ValueType >::stype ( ) const

inline

symmetric type. 0 = nonsymmetric, -1 symmetric lower part, 1 symmetric upper part.

transMult()

template<class ValueType >

virtual Vector< ValueType > GIMLI::SparseMatrix< ValueType >::transMult ( const Vector< ValueType > &  a ) const

inlinevirtual

Return this.T * a
