I was using ZGESVDX routine for incomplete SVD decomposition and noticed cases where the output matrices returned from this subroutine were zero while INFO did not show any error (status...
Greetings, thanks for moving lapack resources to github. i) I wish to remind the old reported bug, http://icl.cs.utk.edu/lapack-forum/viewtopic.php?f=2&t=1820#p11388 , showing up with the newest lapack-3.7.0, as I am reporting here,...
`LAPACKE_?larfb_work` passes `work` and `ldwork` to the Fortran routine unmodified even if the matrix layout is row major. This is extremely surprising bordering a bug because it means that the...
Hello, is someone have some standalone unit-test input/output dataset (error rate, expectation...) for auxiliary functions such as \*lasq\* family any help appreciated. Thank you.
Dear all, I think dstedc produces inaccurate eigenvectors for a specific tridiagonal symmetric matrix. In order to show it, I assembled the attached test. It computes eigenpairs of the Jacobi...
hello dears, i have tried to use the executing the following code, but it seems does not work at least in my point of view, char job,compq; int ldq ,ldt,...

In some cases, DROTMG returns values that, when used in DROTM, do not zero out the second component of the given vector. This can be observed for example with the...
In DGEQP3, line 335-337, we do the panel factorization by JB columns among column J:N. As noticed in DLAQPS, argument F dimension is (LDF, NB)=(N-J+1, JB), so in DGEQP3, we...
Translating Lapack 3.8.0 with a recent gfortran using lto, I get a few lto type mismatches (i.e. the subroutine is called with different arguments than the ones it is declared...
