Follow-up Comment #27, bug #49523 (project octave):
@Dmitri: can you tell me the result of
A = 1i * magic (100) + eye (100);
opts.v0 = (1:100)';
opts.maxit = 7;
d = eigs (A, 10, "sm", opts)
But is it worth/possible to try to construct a set of examples working (that
is, with eigs failing) with any possible combination of blas/lapack/arpack
libraries?
