Fan,

There is a Jagged diagonal matrix class (Epetra_JadMatrix that take an existing Epetra_RowMatrix object as the argument to its constructor.  There is no Ellpack format, although transforming the jagged diagonal class into an Ellpack class would be quite straightforward.

Subject: [EXTERNAL] [Trilinos-Users] Trilinos matrix type

Hello all,

Is there any matrix type other than traditional Trilinos style Crs, Vbr in any of the Trilinos packages?
Specifically, I might cite the format sparse ELLPACK as an example, any possible implementation based on Epetra or Tpetra or Thyra that I could make use of?
I want to be sure about such things to avoid reinventing the wheels.

Thank you for your help.

Best wishes,
Fan
