Webnucleo Technical Report: Wn_Matrix Module

Authors: David C. Adams, Bradley S. Meyer

Abstract: The following report describes some details of the wn_matrix Module, the Webnucleo group's collection of codes for handling sparse matrices. The wn_matrix Module is divided into two parts: 1) routines that deal with creating and managing the WnMatrix structure and 2) routines for performing matrix operations with the WnMatrix structure. This report provides a brief overview of the function and usage of these routines, as well as the WnMatrix structures.

Webnucleo Technical Report: Wn_XML_Utils Module

Author: David C. Adams

Abstract: The following will provide information regarding the routines that comprise the wn_xml_utils Module. The wn_xml_utils Module is intended to supplement libgdome, a library for manipulating XML documents. The routines it contains are used to simplify or expand on some aspects of libgdome's functionality, which they accomplish by utilizing the structures and routines that libgdome provides. This report describes the function and usage of these routines, and provides sample code demonstrating their usage.
