This PR includes some new subroutines of real skew-symmetric matrix. These subroutines include BLAS2/3 operations, linear solver and eigensolver in LAPACK. Please refer to the attachment document for more details....

**Description** I have a deterministic program that uses jax, and is heavy on linear algebra operations. I ran this code on CPU, using three different CPUs. Two MacOs Systems (one...

Type: Bug

This adds a NaN check on the entries of the input matrix A in GEEV, GEEV would now return error `INFO = -4` if there are NaNs in matrix A...

**Description** See https://github.com/OpenMathLib/OpenBLAS/issues/5250 for full context and reproducer Calling ?GEEV with non-finite input will fail in ?HSEQR. ?GEEV will then invoke ?LASCAL to undo any previous scaling of the input...

Building on ALT Workstation K 11.1 (Nemorosa) with following arguments: ``` -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON \ -DCMAKE_STRIP:FILEPATH="/bin/echo" \ -DBLAS_goto2_LIBRARY:FILEPATH=%_libdir/libopenblas.so \ -DCBLAS=ON \ -DUSE_XBLAS:BOOL=ON \ -DBUILD_DEPRECATED:BOOL=ON \ -DBUILD_SHARED_LIBS:BOOL=ON \ -DBUILD_STATIC_LIBS:BOOL=OFF \ ``` ``` [...

**Description** Hey Y'all! I implementted some performance improvements for computing the explicit Q factor in the X{or,un}gY routines. This takes 2 forms. 1) I added an xlarfb that takes into...

Hello everyone! I have like theoretical question connecting with SYEVX algorithm. I ask community to help me with understanding, please. If we are talking about matrices (N ~ 3000) with...

**Description** This PR fixes and closes #1077 and: 1. Adds this description of NaN/Inf propagation quirks to the ?GEMM docs: ``` Note: if alpha and/or beta is zero, some parts...

I have successifully compiled lapack.dll through https://icl.utk.edu/lapack-for-windows/lapack/index.html#build by MinGW. But I need lapack.lib and blas.lib and there weren't any. I couldn't find any way in your instruction. How to obtain...

Type: Question

Call *rot instead of *lasr to perform eigenvector update of *steqr to fully utilize blas subroutines. Code equivalence is verified with norm $\Vert{A-ZDZ^T}\Vert_2$. Entries is generated randomly. Single Precision Case...
