Follow-up Comment #10, bug #53719 (project octave): @Dan: sorry for the zip file, which misses debug.h and contains subfolders. I uploaded a new one. I did not notice the problem with the number of converged ritz values: so, there is probably something in my fortran file or in ARPACK itself. In this example sigma is zero. So inv(A-sigma M) is inv(A) which is a diagonal matrix. Therefore, I divided x by the diagonal of A.
