inconsequential eigs.cc test failure

[Ben Abbott]

I occasionally get the failure below.

  ***** testif HAVE_ARPACK
 [v1,d1] = eigs(A, k, 'si');
 d1 = diag(d1);

  assert(max(abs((A - d1(i)*eye(n))*v1(:,i))),0.,1e-11)
 endfor

Is there any objection to an increase in the tolerance for the test  
script?
