This is the callback function for the first edit text box.
function edit1_Callback(hObject, eventdata, handles)
% save the data from the edit text box in the handles structure in double format.
handles.in1 = str2double(get(hObject,'String'));
% Store the handles structure in hObject.
guidata(hObject,handles);
You will have a similar callback for the second edit box. Now the following is the code snippet for the push button callback.
function pushbutton1_Callback(hObject, eventdata, handles)
% get the previously stored data in myh variable.
myh = guidata(hObject);
% get the values of in1 and in2 in variables x and y. These values come from edit text boxes.
x = myh.in1;
y = myh.in2;
figure;
plot(x,y,'r','LineWidth',2);
I hope this helps !
