edit   text  1 输入         阶数

function zeta_edit1_Callback(hObject, eventdata, handles)
M=str2num(get(handles.zeta_edit1,'string'));
handles.zeta_edit1=M;

edit   text  2 输入         通带频率

function zeta_edit2_Callback(hObject, eventdata, handles)
wp=str2num(get(handles.zeta_edit2,'string'));
handles.zeta_edit2=wp;

edit  text  3 是输入    截至频率

function zeta_edit3_Callback(hObject, eventdata, handles)
ws=str2num(get(handles.zeta_edit3,'string'));
M=handles.zeta_edit1;
wp=handles.zeta_edit2;
wc=(ws+wp)/2;
hd=ideal_lp(wc,M);
w_ham=hamming(M);
h=hd*w_ham;
[db,mag,pha,grd,w]=freqz_m(h,[1]);
delta_w=2*pi/1000;
Rp=-(min(db(1:1:wp/delta_w+1)));
RP=0.0394
As=-round(max(db(ws/delta_w+1:1:501)));
As=52
axes(handles.axes1);
stem(n,hd);
axes(handles.axes2);
stem(n,w_ham);
希望有高人指点。

edit   text  1 输入         阶数

function zeta_edit1_Callback(hObject, eventdata, handles)
M=str2num(get(handles.zeta_edit1,'string'));
handles.zeta_edit1=M;

edit   text  2 输入         通 ...

警告可以不管，至于 ??? Index exceeds matrix dimensions. 的错误，请看置顶贴
