matlab gui 传递函数的实现不能出结果

Question

求离散系统的传递函数

global Ax Ay G
x=get(handles.edit1,'String');
y=get(handles.edit2,'String');
Ax=str2num(x);
Ay=str2num(y);
G=tf(Ax,Ay,1);
set(handles.text2,'String',G);

Answer 1

可以这样写：

global Ax Ay G
x=get(handles.edit1,'String');
y=get(handles.edit2,'String');
Ax=str2num(x);
Ay=str2num(y);
Gstr = poly2sym(Ax,sym('s'))/poly2sym(Ay,sym('s'))
set(handles.text2,'String', string(Gstr));
