Details:
sqp(x0,@f,@g,[])
and
sqp(x0,@f,@g,[],[],[])
solve the same optimisation problem, but the latter produces different output
and runs differently. This is because the code sets lb (ub) to a vector of
length(x0) with entries -Inf (Inf). This is unnecessary and undocumented
behaviour.
I have attached a patch to correct this.
