On my Deiban sid system (amd64) with Octave3.0.5, the test of basisfunder
fails with the following error message:

#########################################################################
  ***** test
 k    = [0 0 0 0 1/3 2/3 1 1 1 1];
 p    = 3;
 u    = rand (100, 1);
 i    = findspan (numel(k)-p-2, p, u, k);
 ders = basisfunder (i, p, u, k, 7);
 for ii=1:10
   sumders = sum (squeeze(ders(ii,:,:)), 2);
   assert (sumders(1), 1, 1e-15);
   assert (sumders(2:end), zeros(rows(squeeze(ders(ii,:,:)))-1, 1), 1e-13);
 endfor
 assert (ders(:, (p+2):end, :), zeros(numel(u), 8-p-1, p+1), 1e-13)
 assert (all(all(ders(:, 1, :) <= 1)), true)
!!!!! test failed
error: invalid conversion from matrix to real row vector

I am unable to debug this problem.  Any hint?
