Hello!

When I use qp-command in octave, I got this error when I'm using to large
matricies:

"ans =

   19   19

ans =

   19    1

ans =

   19    1

ans =

   19    1

warning: operator *: nonconformant arguments (op1 is 18x18, op2 is 19x1)"

I'm using this code:

    size(H)
    size(q)
    size(LB)
    size(UB)
    x = qp([], H, q, [], [], LB, UB)

It's like the H matrix loses one row and one column. Why? Do I compute to
fast? I trying to compute as fast as possible because I want to do adaptive
control for real time controllers.
