Re: RelLineSrchBnd option for fmincon

Many years later I am stuck with the same question...
I THOUGHT that RelLineSrchBnd would adjust the stepsize for the next iteration. So lets say: Iteration 0, X=0; Iteration 1, without RelLineSrchBnd => X=10; %as determined by algorithm
and now let's say I use RelLineSrchBnd then: Iteration 1, with RelLineSrchBnd=0.2 => X=2; %because the stepsize was 1, times 0.2 give X=2;
But this is not what happens... the algorithm takes X=10 again. So what does RelLineSrchBnd do then?
