Bonjour à tous,
J'utilise matlab guide pour faire une interface graphique à mon programme.
En gros, j'ai 3 "push button", chaqu'un lance un sous-programme qui inclut une boucle infinie.
Je voudrais savoir, comment arrêter une boucle infinie lorsque j'appuye sur un autre bouton pour que ce dernier prend le relais.

Ci-dessous le code.
Merci.

Code :

function varargout = test3(varargin)
% TEST3 MATLAB code for test3.fig
%      TEST3, by itself, creates a new TEST3 or raises the existing
%      singleton*.
%
%      H = TEST3 returns the handle to a new TEST3 or the handle to
%      the existing singleton*.
%
%      TEST3('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in TEST3.M with the given input arguments.
%
%      TEST3('Property','Value',...) creates a new TEST3 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before test3_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to test3_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

Bonjour,

Une solution (il y a peut-être plus simple) :
avec a=0 dans la PP
