fminsearch error

[Sivahari Nandakumar]

operator =: no conversion for assignment of 'scalar struct' to indexed '

This error showed in the line

[k,y] = fminsearch(@sig_func,k0,optimset('TolX',1));

I saw the discussion going in the following thread. But it says the problem is still not solved.

Is there any idea?
