Re: Where is UMFPACK available?

[Keith Goodman]

On Debian I installed libumfpack4 and libumfpack4-dev with apt-get. I
don't know if you need both. But it can't hurt.

If your package management system doesn't have umfpack, here's some
information and links to source code:

http://directory.fsf.org/science/math/umfpack.html

Here's what the Debian package descrption says:

set of routines for solving unsymmetric sparse linear systems
UMFPACK is a set of routines for solving unsymmetric sparse linear systems,
Ax=b, using the Unsymmetric MultiFrontal method. Written in ANSI/ISO C, with
a MATLAB (Version 6.0 and later) interface. It appears as a built-in routine
(for lu, backslash, and forward slash) in MATLAB 6.5.

The new code is typically faster than V2.2.1, uses dynamic memory
allocation, and has a symbolic preordering and analysis phase that also
reports the upper bounds on the nonzeros in L and U, flop count, and memory
usage in the numeric phase. It includes a Matlab interface. V4.0 is for real
and complex matrices, rectangular and square, and both non-singular and
singular.
