Here you do frequency sweep from minus frequency to plus frequency.
But you can get minsu frequency response from plus frequency response since "I(-freq)=conj(I(freq))" and "Q(-freq)=conj(Q(freq))" are satisfied.
So you don't have to do frequency sweep of minus frequency.
i try it,but the function complex dont support and i cant not find it in the calulator
the message is *Error* ("complex" 3 t nil ("*Error* complex: argument #1 should be a number (type template = \"n\")" drwave:92266632))
