System Preprocessors

A linear system is a special case of a numerical problem. This file contains the routines for creating, deleting, and duplicating linear systems.
Transformations for linear systems
Eliminate fully determined (singleton) rows from a matrix
Approximate the coefficient matrix
The linear package for SysPro can use the NMD and AnaMod libraries, but does not require them. Any dependencies on NMD and Anamod should all be restricted to computec.
The mechanism of preprocessed solving through forward and backward transformations can be applied to all sorts of numerical problems. At present, we only supply code for linear system solving; see linearfile.
