3. LAPACK 3.6.0: What’s new

  • [Philippe Theveny, UC Denver] BLAS3 routines for generalised SVD

xGGSVD3 and xGGSVP3. Use Level 3 BLAS algorithm. xGGSVD3 uses xGEQP3, xGGSVP3 uses xGGSVD3. This replaces the deprecated subroutines xGGSVD and xGGSVP. xGGSVD3 was using xGEQPF, xGGSVP was using xGGSVD.

  • [Daniel Kressner and Meiyue Shao] Improvements to QR (NEP)

Improvements to nonsymmetric generalized eigenvalue problems xGGHD3: blocked Hessenberg-triangular reduction routines, xGGHD3, for nonsymmetric generalized eigenvalue problems. This replaces the current unblocked routines xGGHRD. CONTRIBUTION BY Daniel Kressner and Meiyue Shao
