rgeev.f is a corrected (lines 180-1) version of dgeev.f, to allow
|
- |
|
| 14 |
LWORK queries to run. (Late versions of dgeev.f are corrected.) It
|
- |
|
| 15 |
calls DLANGE, which was missing in libsunperf, so a renamed copy of
|
- |
|
| 16 |
that is included. Similarly, a renamed copy of LSAME is included as
|
- |
|
| 17 |
that is not exported by MacOS's vecLib.

The routines dsyev and dsyevr have their names remapped to r* unless
|
- |
|
| 20 |
HAVE_LAPACK is defined. This ensures that the versions in rsyev.f
|
- |
|
| 21 |
are called even if an external BLAS library contains LAPACK. This was
|
- |
|
| 22 |
necessary on 64-bit Solaris where the routines in libsunperf were
|
- |
|
| 23 |
picked up and used excessive amounts of memory. In principle it might
|
- |
|
| 24 |
be necessary to extend this remapping to the other symbols used from
|
- |
|
| 25 |
LAPACK.
