Detailed Description


Epetra_CrsMatrix: A class for constructing and using real-valued double-precision sparse compressed row matrices.

The Epetra_CrsMatrix class is a sparse compressed row matrix object. This matrix can be used in a parallel setting, with data distribution described by Epetra_Map attributes. The structure or graph of the matrix is defined by an Epetra_CrsGraph attribute. In addition to coefficient access, the primary operations provided by Epetra_CrsMatrix are matrix times vector and matrix times multi-vector multiplication.
Epetra_CrsMatrix matrices can be square or rectangular.
