It is very important the new smtbx code relying on BLAS 3 is part of nightly tests but Pascal is right here. The only problem is that netlib reference BLAS is written in FORTRAN. So is LAPACK. Both have C interfaces but the actual implementation is in FORTRAN. We could of course run fable on it. In case you do not know Pascal, fable is a tool written by Ralf to convert Fortran to C++.</div><div class=""><br class=""></div><div class="">Best wishes,</div><div class=""><br class=""></div><div class="">Luc</div><div class=""><br class=""></div></body></html>
