Details:

finding a root of this function bg_f:


function [f, jac] = bg_f(x)
  f   = x;
  jac = 1;
end


with fsolve in this script:


ver = version
opts = optimset('Jacobian', 'on', 'Updating', 'off');
sol = fsolve(@bg_f, 1, opts)


produces on 4.1.1:


ver = 4.4.1
sol = 0


on dev, the correct solution, but with some warnings:


ver = 5.0.0
warning: optimget: unrecognized option: OutputFcn
warning: called from
    optimget at line 45 column 5
    fsolve at line 200 column 10
    bg at line 3 column 5
warning: optimget: unrecognized option: TypicalX
warning: called from
    optimget at line 45 column 5
    fsolve at line 206 column 12
    bg at line 3 column 5
sol = 0
