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.

int *  BlockIndices 
)

Initiate replacement of current values with this list of entries for a given global row of the matrix, values are replaced via SubmitEntry()

Parameters
InRow - Block Row number (in global coordinates) to put elements.
InNumBlockEntries - Number of entries.
InIndices - Global column indices corresponding to values.
Returns
