用于电力系统的一个很好的分析软件

function b = subsref(a,index)

switch index(1).type
 case '.'
  switch index(1).subs
   case 'con'
    if length(index) == 2
      b = a.con(index(2).subs{:});
    else
      b = a.con;
    end
   case 'u'
    if length(index) == 2
      b = a.u(index(2).subs{:});
    else
      b = a.u;
    end
   case 'bus'

   case 'vref'
    if length(index) == 2
      b = a.vref(index(2).subs{:});
    else
