Detailed Description

Epetra Finite-Element VbrMatrix. This class provides the ability to input finite-element style sub-matrix data, including sub-matrices with non-local rows (which could correspond to shared finite-element nodes for example). This class inherits Epetra_VbrMatrix, and so all Epetra_VbrMatrix functionality is also available.

Epetra_FEVbrMatrix::Epetra_FEVbrMatrix (  Epetra_DataAccess  CV,
const Epetra_BlockMap &  RowMap,
int *  NumBlockEntriesPerRow,
bool  ignoreNonLocalEntries = false
) 
 

Epetra_FEVbrMatrix constuctor with variable number of indices per row.

Creates a Epetra_FEVbrMatrix object and allocates storage.

Parameters:
In CV - A Epetra_DataAccess enumerated type set to Copy or View.
In RowMap - A Epetra_BlockMap listing the block rows that this processor will contribute to.
In NumBlockEntriesPerRow - An integer array of length NumRows such that NumBlockEntriesPerRow[i] indicates the (approximate) number of Block entries in the ith row.

Reimplemented from Epetra_VbrMatrix.

int Epetra_FEVbrMatrix::PutScalar (  double  ScalarConstant  ) 
 

Initialize all values in graph of the matrix with constant value.

Parameters:
In ScalarConstant - Value to use.
Returns:
Integer error code, set to 0 if successful.

Reimplemented from Epetra_VbrMatrix.
