[Octave-bug-tracker] [bug #58926] Octave gives wrong results with intel-mkl when diagonalizing large matrices

[anonymous]

Follow-up Comment #25, bug #58926 (project octave):

Unfortunately the fntests.log files don't seem to give any reason for the
crash. The assertion failure between real and complex is pretty blatant
though, even with the MKL_THREADING_LAYER workaround. That is a no-go for
anyone who wants to use Octave with MKL, at least the versions that OP
downloaded from the distro repositories.

Overall, I don't see how we can do better in this case than documenting the
problem, suggesting the MKL_THREADING_LAYER workaround, and asking the user to
test the output. At least future users trying the same combination can find it
either in the manual or in this bug report.

@OP: I saw in your linked forum posts that you asked the MKL team to document
it as well. Do feel free to try it again in future as new versions of MKL are
released, or if you want to build Octave from source yourself and link with
IOMP, etc. But that will have to be on your own. If you find anything that
works, please consider a wiki HOWTO entry.
