Name        : arpack
Product     : Fedora 21

Summary     : Fortran 77 subroutines for solving large scale eigenvalue problems
Description :
ARPACK is a collection of Fortran 77 subroutines designed to solve large
scale eigenvalue problems.

The package is designed to compute a few eigenvalues and corresponding
eigenvectors of a general n by n matrix A. It is most appropriate for
large sparse or structured matrices A where structured means that a
matrix-vector product w <- Av requires order n rather than the usual
order n**2 floating point operations. This software is based upon an
algorithmic variant of the Arnoldi process called the Implicitly
Restarted Arnoldi Method (IRAM).

Update Information:

Upstream changes since 3.1.3:
* Build all examples and run them as tests
* Fix the version of arpack-ng itself
* Switch to automake 1.14.1
* Do not install test binaries (Closes: #1348)
* Fix the diagonal matrix example (dndrv5) (Closes: #1397)
* Replace LAPACK second function with ARPACK's own arscnd in PARPACK
* Fix issue #1259 in DSEUPD and SSEUPD The Ritz vector purification step assumes workl(iq) still contains the original Q matrix. This is however overwritten by the call to xGEQR2 earlier. This patch fixes the issue by making a copy of the last row of the eigenvector matrix, after it is recomputed after QR by xORM2R. The work space WORKL(IW+NCV:IW+2*NCV) is not used later in the routine, and can be used for this.
* Switch to automake 1.14 + libtool 2.4.2. Thanks to Ward Poelmans (Closes: #1321)
* dseupd routine may lead to a segmentation fault Thanks to Edouard Canot (Closes: #1323)
* dsaupd and 'BE' option returns wrong eigenvalues for a SPD matrix Thanks to Edouard Canot (Closes: #1329)
