[Rik]

Update of bug #36923 (project octave):

                  Status:         Patch Submitted => Need Info

Follow-up Comment #1:

The same effect can be had by changing line 192 of fminbnd.m from


if (fu <= fval)


to


if (fu < fval)


There is the following comment in the original code:


## The following if-statement was originally executed even if fu == fval.


By dropping the '=' the code goes back to the "original", whatever that means.
 I'm tempted to use this fix since it means 2 fewer function evaluations,
however I don't pretend to have studied the algorithm and know if this is
okay.
