How do I make this fmincon function work. The optimization output fval is supposed to have influence on the condition vector A.
1) If I predefine fval, A is not depending on the optimization output. 2) If I make a loop statement and duplicate the optimization problems, then saying that the loop must stop once x(1st. optimization) – x(2nd. optimization) = 0, matlab cannot solve this because in case the latter fmincon function did not find any solution (my case), the iteration simply is repeated xxx times.
In Excel this is a question of seconds – I have spend about two weeks with this problem – any help !
A = [fval*5]; B = [5]; ffun = @(x)x^3 + x^4; [x fval] = fmincon(ffun,1,[],[],A,B,[],[]);
