This directory contains the M-files for sparse QR factorization discussed 
in the report, Matstoms, "Sparse QR factorization in MATLAB", 1992. The
implementation is based on the sparse extension of MATLAB introduced in
version 4. A version number 4.0.BETA.3 or higher is therefore assumed.

A code description (calling sequences etc.) is given in PostScript format
in the file description.ps.Z

                          ----------------------
   
The M-files are available under the following conditions.

   o The code is used only for non-commercial purposes in education
     and research.

   o The origin notice shall be retained in all copies.

   o The code is made available without any guarantees. Both the University
     of Linkoping and myself disclaim all implied warranties.

   o You send me your name and institution as soon as you have transfered
     the files.
