How to evaluate symbolic expressions with the subsfunction in MATLAB?

Evaluating symbolic expressions with the subsfunction is time-consuming. It is much more efficient to use matlabFunction. matlabFunctiongenerates code that depends on the orientation of input vectors. Since fminconcalls the objective function with column vectors, you must be careful to call matlabFunctionwith column vectors of symbolic variables.
