Bonjour,

Excusez moi, mais j'ai vraiment du mal avec cette interface graphique :

Voilà mon code :

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

La réponse de Matlab est la suivante :
??? Error using ==> feval
Undefined function or method 'Calcul_Callback' for input arguments of type 'double'.

Error in ==> gui_mainfcn at 96
feval(varargin{:});

Error in ==> projet at 42
gui_mainfcn(gui_State, varargin{:});

Error in ==> @(hObject,eventdata)projet('Calcul_Callback',hObject,eventdata,guidata(hObject))


??? Error while evaluating uicontrol Callback
En fait, je ne comprends pas ce qu'il veut car je n'ai pas de feval donc aucune idée d'où provient l'erreur, pouvez-vous m'aider?

Merci d'avance.
