no.uib.cipr.matrix

Class DenseVectorSub

java.lang.Object

no.uib.cipr.matrix.AbstractVector

no.uib.cipr.matrix.DenseVectorSub

All Implemented Interfaces:

Serializable, Iterable<VectorEntry>, Vector

public class DenseVectorSub
extends AbstractVector

Wraps a DenseVector, allowing easy access to a sub array of the original without taking copies.

It should be possible to utilise BLAS / LAPACK in various matrix classes. However, as it would be a mammoth task, it will be done on an as-needed basis.
