I'm attaching a Fortran code which demonstrates the problem. The code reads two diagonal matrix from a file in the binary format and call DBDSDC: CALL DBDSDC( 'U', 'I', N,...
When I use the 2stage routine of dsyevr, I get the following error message: ` ** On entry to DGEQRF parameter number 7 had an illegal value` The same usage...
hi，I encountered this problem when I compiled it. stbt05.f: In function 'stbt05': stbt05.f:189: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. See...
@langou : @phcerdan and I will start working on the following * [ ] Do not require `Fortran`. See https://github.com/Reference-LAPACK/lapack/blob/9fb29d8ea47d643ad44a67d3da5de36e280143f5/CMakeLists.txt#L3 * [ ] Add option `LAPACK` enabled by default (similar...

In https://github.com/xianyi/OpenBLAS/issues/1689 the issue was raised that OpenBLAS provides its own implementations of the BLAS extensions CSBMV and ZSBMV, as these clash with local implementations in TESTING/EIG and TESTING/LIN when...
The first line of dgegs.f and dgegv.f has the description *> \brief DGEEVX computes the eigenvalues and, optionally, the left and/or right eigenvectors for GE matrices This is particularly confusing...
For M=0 or M=0, GESVD returns a zero matrix for VT or U, respectively. Mathematically correct would be to return an identity matrix.
Documentation of RANK claims that it would contain the rank of A after the call to GELSY. However, if there are no right-hand side vectors (NRHS=0) then the returned RANK...
