Detailed Description

Epetra_OskiVector: A class for constructing and using dense OSKI vectors on a single processor or a single core of a multi-processor.

The Epetra_OskiVector class enables the construction and use of real-valued, double-precision dense vectors in a serial environment. The dimensions of the dense vectors comes from the inherited Epetra_Vector object. All values and data layouts are kept the same and the vector is wrapped for use with OSKI.
