There's an example at the link below.

Specifically,

%!test
%! C = [rotdim(2.^(2:7)*1e8,-1), ones(6,1), rotdim(2.^(3:8),-1)  
ones(6,1)];
%! d = [58.6; 30.0; 15.2; 7.7; 3.9; 2.1];
%! x = [2.3357e-6; 0.4229; 0; 0];
%! assert (lsqnonneg (C, d), x, 0.0001)

It fails for me .... however, my current build of Octave might be  
suspect.
