We got asked to find the max value of a function using "fminbnd", got that part, the closest to the real value gets rewarded. How do I know if I could be closer?
x=-10:0.01:10;
options1=optimset('TolFun',1e-7);
[xa,fval1] = fminbnd(fneg,x1,x2,options1);

Hi ,
fminbnd function returns the point where the function takes minimum value in the given interval and fval1 need not be maximum value.
The detailed explanation can be found here : Find minimum of single-variable function on fixed interval - MATLAB fminbnd (mathworks.com)
