I would like to know how I could use the the values for num, den and sys I have in function untitled_OpeningFcn and use them on the pushbutton1_Callback function for the graphs and setting of the values of the text boxes.
function untitled_OpeningFcn(hObject, eventdata, handles, varargin)
handles.output = hObject;
guidata(hObject, handles);
if strcmp(get(hObject,'Visible'),'off')
t = 0:0.25:7;
y = sin(t);
plot(t,y)
end
num = input('Enter coefficients of numerator: ');
den= input('Enter coefficients of denominator: ');
sys = tf([num],[den]);
display('Your transfer function is: '); sys
function pushbutton1_Callback(hObject, eventdata, handles)
if true
end
axes(handles.axes1);
cla;
set(handles.numtxt, 'String', num2str(num));
set(handles.dentxt, 'String', num2str(den));
popup_sel_index = get(handles.popupmenu1, 'Value');
switch popup_sel_index
case 1
pzmap(sys);
case 2
rlocus(sys);
case 3
nyquist(sys);
case 4
bode(sys);
end
