Bonjour,
J'essaye de créer une interface graphique que GUIDE de Matlab.
Pour l'instant mon exemple est une simple addition. On rentre les deux facteurs par un textedit et en appuyant sur un bouton on obtient le résultat.
Je souhaite récupérer les facteurs et le résultat en sortie.
En suivant l'exemple donné dans la foire aux questions j'ai ce code :


Code : Sélectionner tout - Visualiser dans une fenêtre à part

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

Mais quand je le fais tourner, aucunes sorties n'est renvoyées et je ne comprends pas pourquoi.
Quelqu'un peut m'aider?
Merci d'avance !
