[Octave-bug-tracker] [bug #57460] Tolerance exceeded in test for "svds" on Windows

[Rik]

Follow-up Comment #4, bug #57460 (project octave):

Interestingly, the failing test does not use the random number generator to
initialize the starting search point for ARPACK.  To do that, Octave has to
pass the opts structure.  The first test that is failing is just calling "svds
(A, k)".

In this case, ARPACK chooses its own random starting point.  That means, it
may be just random bad luck that sometimes it fails and sometimes it doesn't.

Could you run the following benchmark which I have attached in two files
(tst_svds.m and stats_tst_svds.m)?  Download the files, put them in the same
directory, start octave, and then run "stats_tst_svds"

(file #48110, file #48111)
