EpetraExt::BlockCrsMatrix::BlockCrsMatrix (  const Epetra_CrsGraph &  BaseGraph,
const std::vector< int > &  RowStencil,
int  RowIndex,
const Epetra_Comm &  GlobalComm
) 
 

BlockCrsMatrix constuctor with one block row per processor.

Creates a BlockCrsMatrix object and allocates storage.

Parameters:
In BaseGraph - Graph determining individual block structure, can be distrib. over subset of proc.'s
In RowStencil - Describes the stencil for block row on this processor (i.e. (-1 0 1) centered difference)
In RowIndex - Defines the index used for this block row.
