Constructor & Destructor Documentation

DenseSerialMatrix::DenseSerialMatrix ( const VectorSpace< double > &  domain,
const VectorSpace< double > &  range 
)

Construct with domain and range spaces, which should be DenseSerialVectorSpace objects

Definition at line 72 of file PlayaDenseSerialMatrix.cpp.

Playa::DenseSerialMatrix::~DenseSerialMatrix ( ) [inline]

Virtual dtor

Definition at line 79 of file PlayaDenseSerialMatrix.hpp.

Member Function Documentation

void DenseSerialMatrix::addToRow ( int  globalRowIndex,
int  nElemsToInsert,
const int *  globalColumnIndices,
const double *  elementValues 
) [virtual]

Insert a set of elements in a row, adding to any previously existing values. The nonzero structure of the matrix must have been determined at construction time.

Parameters:
globalRowIndexthe global index of the row to which these elements belong.
nElemsToInsertthe number of elements being inserted in this step
globalColumnIndicesarray of column indices. Must be nElemsToInsert in length.
elementsarray of element values. Must be nElemsToInsert in length

Implements Playa::LoadableMatrix< double >.
