Detailed Description

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

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