Release date: 11/12/17.

This material is based upon work supported by the National Science Foundation and the Department of Energy under Grant No. NSF ACI 1339797, NSF-OCI-1032861, NSF-CCF-00444486, NSF-CNS 0325873, NSF-EIA 0122599, NSF-ACI-0090127, DOE-DE-FC02-01ER25478, DOE-DE-FC02-06ER25768.

LAPACK is a software package provided by Univ. of Tennessee, Univ. of California, Berkeley, Univ. of Colorado Denver and NAG Ltd..

2. LAPACK 3.8.0: What’s new

2.1. Symmetric-indefinite Factorization: Aasen’s tridiagonalization 2 stage

A contribution from Ichitaro Yamazaki (University of Tennessee).

This is the blocked version of Aasen’s factorization for symmetric-indefinite factorization. The algorithm calling Level 3 BLAS.

Added:
