Package org.spaceroots.mantissa.linalg Description

This package provides classes to perform linear algebra computation.

It is by no means a complete linear algebra system, it is sufficient to solve least squares problems and linear equations systems, but it lacks lots of functionalities and matrices types (for example sparse matrices are not supported).

The class diagram for the public classes of this package is displayed below. The user will mainly use directly the implementation classes rather than the abstract Matrix class. The shape of the matrices used is often known in the algorithms so there is little need to hide this shape behind the general class.
