Function usefielddependent_n(indEl, matind ,Ex,Ey,T,xp,yp) is activated by the command $usefieldmufunc. This function is similar to command $useemunfunc, $useemupfunc. But this function provide more parameters for use to assign in the input file. Therefore, this function can be continuous expanded to many different mobility models.
