Optimization with fminsearch and looping

I have this code. t = a; s = c;

for k0 = [0.2 0.5 1 1.5]:[0.25 0.6 1.1 1.6]

    [k,fval,exitflag,output] = fminsearch(@(k) suki(s, t, k), k0)

    if fval <= 1
        disp('Convergence has worked.')
    elseif fval >= 1
        disp('The convergence is not good enough')
    end

end

Error message comes up as: Attempted to access k(2); index out of bounds because numel(k)=1. I need ideas on how to correct this and get the fminsearch iterations for the range of values of the initial vector k0. Thanks.

What does suki do?

Hi,

what do you expect

[0.2 0.5 1 1.5]:[0.25 0.6 1.1 1.6]

to be? In fact it's 0.2, and I guess your suki expects a vector for k ...
