ARPACK with Autotools Description

The tried-and-true eigensolver, with a modern build system. ARPACK with Autotools is a distribution of ARPACK, the well-known sparse eigensolver, with a number of changes:* the most recent patches from the ARPACK download page applied* a nasty, potentially crashing bug fixed* the build system replaced by autoconf/automakeDeveloper commentsNote that ARPACK is not my own work, I am only redistributing a modified version. I contacted Rich Lehoucq years ago with a report of the crash bug, but the fix never showed up on the ARPACK page, so I resorted to distributing my own modified ARPACK package. Since ARPACK continues to be useful for my work, but its rather old-fashioned build system kept getting in my way, I one day decided to replace it with a modernized, autotoolized version, so that it can be built on most machines with just the regular./configuremakemake installincantation. Additionally, the new build system makes it trivial to build a shared library of ARPACK. Since there doesn’t seem to be a proper version-numbering scheme at ARPACK’s original site, I’ve also taken the liberty of starting at version 0.90.
