On line qp.m:393, H has some small complex components that creep in:
debug> max(max(abs(imag(H))))
ans = 1.5047e-009
If I change line 393 in qp.m to the following, it seems to work.
[x, lambda, info, iter] = __qp__ (x0, real(H), real(q), A, b, Ain, bin,
maxit);
That change scares me, but maybe it will point more intelligent people than I
towards the real solution.
