Hi Martin, this is a good point. I am glad to learn that OpenBLAS added CSBMV and ZSBMV to the OpenBLAS library. I understand the problem that is caused when...

After further reflection, it might make sense to move this functionality (CSBMV and ZSBMV) in the LAPACK library. Would that work for OpenBLAS? Or would that not fix the problem?

Hi Aisha, that makes total sense to me, but let us see if we have feedback from others. So let us wait a few days. J

Hi all, Reference BLAS, reference CBLAS, reference LAPACK, two of the main thrusts of these projects are (1) numerical algorithms and (2) defining common interfaces, a reference implementation and a...

To add some context, the CBLAS was born from a committee (the Basic Linear Algebra Subprograms Technical Forum) that worked from 1996 to 2000 on revisiting the BLAS, as part...

Thanks @AlexanderZotkevich. Nice. Indeed a random matrix is almost always well-conditioned, and consequently so is an R factor of one of its QR factorization. But, if we change the diagonal...

Hi @h-vetinari, Yes this is a good idea. (1) we could write higher levels wrappers that would call the "best" function. The current structure (clean interface for a stand alone...

Hi @christoph-conrads ! I received a few comments by email about GGQRCS. Mostly very positive reviews! However, there are some outstanding questions and (1) I do not know the answers...

Hi @ilayn, there is no ``info`` parameter in TRSM.

Hi @chtobler, This relates to ``Section 2.3.3 TRSV and TRSM`` of the document sent in August 2021 by Jim Demmel ``Proposed Consistent Exception Handling for the BLAS and LAPACK``. The...
