* Replace LAPACK second function with ARPACK's own arscnd in PARPACK
* Fix issue #1259
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.
is this 3.1.4 release already final? I wonder why there is no tag in the git repo.
Also in configure.ac is still 3.1.3 set.
BTW the new tar ball name arpack-ng_3.1.4.tar.gz with underscore instead of minus indicates that it was somehow manually created instead of using "make dist". Make dist would have also shown you the wrong version number.
