Matlab - Buttom group

Tengo un buttom group con 3 opciones, según que botón escojas se le da un valor a un parámetro A y B. Después, al pulsar un pushboton quiero que me aparezca una gráfica. Os pongo el código correspondiente:

% --- Executes when selected object is changed in uipanel1.
function uipanel1_SelectionChangeFcn(hObject, eventdata, handles)
% hObject handle to the selected object in uipanel1
% eventdata structure with the following fields (see UIBUTTONGROUP)

if (hObject==handles.uno)
A=1;
B=5;
elseif hObject==handles.dos
A=2;
B=3;
elseif hObject==handles.tres
A=3;
B=1;
end
% EventName: string 'SelectionChanged' (read only)
% OldValue: handle of the previously selected object or empty if none was selected
% NewValue: handle of the currently selected object
% handles structure with handles and user data (see GUIDATA)


% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
x=[A A+1 A+2];
y=[B 0 B];
axes(handles.axes1)
plot(x.y)

Me indica que no conocen el valor de A y B. ¿por qué?

Hola JJ.
Hice unos arreglos, a tu codigo que acabas de copiar, me gustaria ver tu codigo completo.
Porque derepente hay mas errores, por motivos de tag y otros variables.
Apesar de los arreglos que te acabo hacer a tu codigo, aun sigue fallando, entonces si desea me envias tu codigo ami correo para poder verlo y filtrarte, ya que un interface tiene dos aspectos, un archivo *.fig y un archivo *.m y eso hay veces ocaciona que uno no pueda dar una respuesta correcta a las preguntas sobre guide.
Porque ademas reproducir el guide que estas haciendo implica tiempo.

Muchas gracias Jose por contestar, este es el código:
function varargout = untitled(varargin)
% UNTITLED M-file for untitled.fig
% UNTITLED, by itself, creates a new UNTITLED or raises the existing
% singleton*.
%
% H = UNTITLED returns the handle to a new UNTITLED or the handle to
% the existing singleton*.
%
% UNTITLED('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in UNTITLED.M with the given input arguments.
%
% UNTITLED('Property','Value',...) creates a new UNTITLED or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before untitled_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to untitled_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
%
% See also: GUIDE, GUIDATA, GUIHANDLES

% Edit the above text to modify the response to help untitled

Hola JJ;

Te dejo una segmento de una situación similar:




Espero que sea de alguna ayuda.

Hola JJ.


Este codigo funciona correctamente.
Dereepente el error debe de estar en la creacion de tu guide. En tu guide, tiene que estar activado el primer boton, automaticamente. Y si no esta activado, entonces el error esta alli.
Mira este video, te va a ayudar mucho.



Saludos.
