More details ---------------- *xSYSV_ROOK: LDL^T^ with rook pivoting.* Contribution by Craig Lucas (University of Manchester and NAG) and Sven Hammarling (NAG). These subroutines enable better stability than the Bunch-Kaufman pivoting scheme currently used in LAPACK xSYSV solvers; also, the elements of L are bounded, which is important in some applications. The computational time of xSYSV_ROOK is slightly higher than the one of xSYSV. * New stopping criteria for balancing. * more robust complex division routine [DLADIV]- suggested by Victor Liu contributed by Michael Baudin, Robert L. Smith Source: http://arxiv.org/abs/1210.4539 Robert L. Smith is actually the original inventor of the current algorithm in Lapack. I have attached my modified DLADIV routine, which passes all the tests in the build process. 7. Bug Fix ----------- link:errata_from_342_to_350.html[see here] // vim: set syntax=asciidoc:
