NA Digest, Vol.94, #15, 1994 ============================ From: Cleve Moler Date: Sun, 3 Apr 1994 13:56:14 -0400 Subject: Harwell-Boeing Connection to MATLAB New software is available which facilitates MATLAB access to sparse matrices in the Harwell-Boeing Sparse Matrix collection. The Harwell Boeing collection is available via anonymous FTP from the CERFACS research laboratory in France: orion.cerfacs.fr (130.63.200.33) The collection is in directory pub/harwell_boeing A compressed, postscript file contained a detailed user's guide is pub/harwell_boeing/userguide.ps.Z The new conversion software is available via anonymous FTP from the MathWorks: ftp.mathworks.com (144.212.100.10) There are two files in directory pub/mathworks/toolbox/matlab/sparse The first file is hbo2mat.f, Fortran source code for a stand alone program which reads Harwell-Boeing data files and uses the MATLAB External Interface Library to convert them to .mat files. The second file is hbo.m, a MATLAB function which loads one of the .mat files and completes the conversion. -- Cleve Moler moler@mathworks.com
