test failures

[John W. Eaton]

After the latest sparse changes, I see the following failures:

  >>>>> processing /export/home/jwe/src/octave/scripts/sparse/svds.m
    ***** testif HAVE_ARPACK
   [u2,s2,v2,flag] = svds(a,k,0);
   s2 = diag(s2);
   assert(flag,!1);
   assert(s(k:-1:1), s2, 1e-10); 
  !!!!! test failed
  eigs: sigma must be a scalar or a string  ***** testif HAVE_ARPACK
   idx = floor(n/2);
   % Don't put sigma right on a singular value or there are convergence 
   sigma = 0.99*s(idx) + 0.01*s(idx+1); 
   [u2,s2,v2,flag] = svds(a,k,sigma);
   s2 = diag(s2);
   assert(flag,!1);
   assert(s((idx+floor(k/2)):-1:(idx-floor(k/2))), s2, 1e-10); 
  !!!!! test failed

  >>>>> processing test_sparse

   warning ("off", "Octave:divide-by-zero");
   assert(full(sparse(eye(3))/0),full(eye(3))/0);
   warning (wdbz.state, "Octave:divide-by-zero");
  !!!!! test failed

  but got

  NaNs don't matchshared variables {
    bf = 2.2251e-308 + 2.2251e-308i
  }

I fixed the one in test_sparse.m.

Could someone else take a look a the failing svds tests?

Thanks,
