[sci.math] Linpack-like routines in C

msc_wdqn@jhunix.HCF.JHU.EDU (Daniel Q. Naiman) (06/16/89)

Does anyone out there know of alternatives to Linpack written in the C     
language and for which the source code is in the public domain. It is
important that it have various matrix inversion programs, especially for 
banded matrices. Also, it is important that the programs be written with
numerical issues taken seriously. 

Please post or send mail to

I tend to use the source code from the Numerical Recipees book. I am not
sure whether the code is public-domain---i.e. whether one would be allowed
to write and sell a commercial application incorporating the compiled version
of some of their routines---but for private applications, it is quite reliable,
written nicely in C by experts in the numerics field, available in C source
code for something like $25, and comes with a fat book explaining how each
routines work.
