    Par défaut un petit projet d'analyse numérique
    Bonjour tout le monde
    j'ai un petit projet sur ( GUIDE ) qui permet à l'utilisateur de résoudre des équations différentielles ( d’ordre 1 , d’ordre supérieur + système ) par les méthodes numériques classiques (Euler explicite , Euler implicite , Rk2,Rk4) , de dessiner les solutions et de comparer les solutions exactes avec les solutions obtenues numériquement ( si l’utilisateur connait la solution exacte ) .

    j'ai écrit sur Matlab des fonctions qui permettent de résoudre ces equations différentielles et voilà un exemple :

    ( cas d'euler explicite ) :

    function [t,y] = my_euler_explicite(f,t0,y0,h,nbpas)
    %
    %  Méthode d'Euler pour les systèmes d'équations différentielles
    %    de la forme y'(t) = f(t,y(t)) {SD}
    %
    %  Préalable:
    %  Vous devez créer un fichier .m contenant la fonction f(t,y).
    %  Voir par exemple le fichier eqndiff.m
    %
    %  Exemples d'appel:
    %  [t,y] = my_euler_explicite('eqndiff',0.0,[1 1],1.0e-1,10)
    %
    %  Arguments en entrée:
    %  1) f: Le nom entre apostrophes (' ') du fichier .m contenant la fonction
    %     f(t,y).
    %  2) t0: le temps initial
    %  3) y0: la(les) condition(s) initiale(s), sous la forme d'un vecteur ligne:
    %         par exemple, [1 2]. La dimension de y0 donne la dimension du système
    %  4) h: le pas de temps
    %  5) nbpas: le nombre maximal de pas de temps
    %
    %  Arguments en sortie:
    %  1) t est un vecteur contenant les temps, ti
    %  2) y est une matrice contenant la solution obtenue:
    %     la colonne i de y correspond a la solution de l'équation i
     
    % on fait quelques calculs préliminaires
     
    nbeq = size(y0,2);% détermine le nombre de colonne de la matrice d'initialisation y0 ----> càd le nombre d'équations à résoudre 
    y0 = y0';
    k1 = zeros(nbeq,1);
    y = zeros(1,nbeq);
    n = 1;
    t(1) = t0;
    y(1,:) = y0';
    warning off
     
    % la boucle transitoire
     
    while(n <= nbpas),
     
      % on fait quelques vérifications de base
     
      k1 = feval(f,t(n),y0);
      if (any(~isfinite(k1))),
        disp('la fonction n''est pas definie en certains points');
        return;
      end
     
      % la méthode d'Euler est ici!
     
      y0 = y0 + h * k1;
      y(n+1,:) = y0';
      t(n+1) = t(n) + h;
      n = n+1;
     
    end
    %keyboard
    et voici un exemple d'équation différentielle qui doit être écrite dans un file d'extension (.m) indépendant du premier :

    function f=my_ma_fonction(t,y)
    f=y;

    et voici un exemple d'appel de la fonction euler explixite dans un troisième fichier d'extension (.m)

    [t,y] = my_euler_explicite('my_ma_fonction_1',t0,y0,h,nbpas);

    %vrai valeur de la fonction
     
    yy=exp(-15*t);
    hold on;
    plot(t,yy,'r');
    grid on;
    Le problème est que ma méthode Euler prend en paramètre le nom d'un fichier (.m) contenant la fonction

    l'utilisateur souhaitons résoudre son équation sur l'interface graphique , écrit dans un "edit text" son équation
    Mon problème est que je veux concevoir un push button ( générer file ) , qui permet à l'utilisateur quand il le clique de générer un file (mfile) contenant l'équation à resoudre se trouvant dans l' " edit text " .

    Un deuxième problème s'il vous plait :

    en cas d'un système d'équations différentielles , je souhaite concevoir un push_ button qui permet de générer un nombre d'axes égal au nombre d'équation formant le système .


    Aucun a une idée de programmation qui peut m'aider ??
    merci en avance

    Bonjour,

    Pour ton premier point, regarde du côté des fonctions FOPEN, FPRINTF et FCLOSE, c'est un moyen d'écrire un fichier texte:

    % Ouverture du fichier 'mon_fichier.m' en mode écriture texte
    fid = fopen('mon_fichier.m', 'wt');
     
    % Vérification que l'ouverture du fichier n'a pas retourné d'erreur
    if (fid == -1); return; end
     
    % Ecriture d'une ligne dans le fichier 'mon_fichier.m'
    fprintf(fid, 'Ma fonction est: %s\n', 'ma_fonction');
     
    % Fermeture du fichier
    fclose(fid);
    Pour ta deuxième question, je ne comprends pas bien le problème. Tu devrais y arriver assez simplement avec FIGURE et SUBPLOT (ou AXES). Pourrais-tu nous montrer ce que tu as fais?

    bonsoir
    merci chèr moderateur
    pour les fonctions fopen, fclose , fprint , etc , ça marche très bien
    je suis arrivé maintenant à écrir ma fonction f(t,y) qu'il faut intégrer dans un fichier (.m) qui porte le nom : ma_fonction.m grace a fopen , fprint et fclose
    il suffit maintenant de faire appel à la methode Euler pour obtenir la matrice [t,y] et de faire le plot après
    mais ça marche pas , il ya erreur quelque part et je n'arrive pas à le trouver
    voilà ce que j'ai écrit jusqu'à maintenant :

    les callbacks des objets sont très significatifs de façon qu'il se comprenne lisiblement .
    ex : le tag de l'edit text ou l'on ecrit la fonction à resoudre (celle de 1er ordre ) s'appelle : first_order_equation_edit_text
    et ainsi de suite
    le problème :
    lorsque je remplis les champs ( initial conditions , steps , etc ) , ex :

    http://www.mediafire.com/i/?n3ey70hezczy30v
    puis je choisis du pop-up menu la méthode explicite (par ex) puis je clique sur "done" il m'arrive le message d'erreur suivant sur le command window :

    et bien , qu'est ce que je dois faire ??
    pourqoui il n'arrive pas à identifier ma fonction d'Euler explicite ??

    s'il ya aucune question sur mon code , je suis prêt a expliquer


    Merci en avance

    As-tu essayé de coder quelquechose pour faire cette action?

    Quelques pistes: dans la fonction Callback de ton bouton 'show', utilise GET pour récupérer les informations de ton editbox et la fonction SET pour mettre à jour les données de ta listbox (pense à jeter un oeil sur l'aide de ces fonctions )

    bonsoir les copains
    j'ai un petit problème
    j'ai une listbox en guide qui contient sur la 1ère ligne :1
    sur la 2ème ligne : 2
    sur la 3ème ligne : 3
    sur la 4ème ligne : 4
    sur la 2ème ligne : 5

    j'ai un checkbox qui , quand il coché :
    la propriété 'max' de cette listbox = 2
    la propriété 'min' de cette listbox = 0
    donc j'ai la permission de faire une séléction multiple
    quand non :
    la propriété 'max' de cette listbox = 1
    la propriété 'min' de cette listbox = 0
    donc donc j'ai pas la permission de faire une séléction multiple .
    j'ai écrit dans le callback de cet checkbox , le code suivant :

    Code : Sélectionner tout - Visualiser dans une fenêtre à part
    1
    2
    3
    4
    5
    6
    7
    8
    9
    10
    11
     
    function checkbox1_Callback(hObject, eventdata, handles)
    if((get(handles.checkbox1,'value')) ==(get(handles.checkbox1,'max')))
        set(handles.listbox1,'max',2);
        set(handles.listbox1,'min',0);
    end
    if((get(handles.checkbox1,'value')) ==(get(handles.checkbox1,'min')))
        set(handles.listbox1,'max',1);
        set(handles.listbox1,'min',0);
    end
    guidata(hObject,handles);
    j'ai un pushbutton "Clear"
    qui a pour rôle d'éffacer les éléments séléctionnés de la listbox , j'ai écrit le code suivant :
    Code : Sélectionner tout - Visualiser dans une fenêtre à part
    1
    2
    3
    4
    5
    6
    7
     
    function clear_Callback(hObject, eventdata, handles)
    selected=get(handles.listbox1,'value'); % Le tag du %listbox est 'listbox1'
    for i =1 :length(selected)
        set(handles.listbox1,'string','','value',selected(i));
    end
    guidata(hObject,handles);
    mais ça marche pas , j'ai fais run
    j'ai coché le checkbox s'appelant "allow"
    j'ai séléctionné la ligne 2 et 3 et tous les éléments de la listbox sont éffacés , et non pas seulement ceux qui sont séléctionnées .

    un deuxième problème :
    j'ai un pushbouton 'change' , qui , une fois appuyé , change la valeur séléctionnée de la listbox et la met 'x' par exemple .
    mais ça marche pas !!!!
    une fois cliqué après le "Run" , la listbox disparait et un warning sur le command window apparait signalant la phrase suivante :

    Code : Sélectionner tout - Visualiser dans une fenêtre à part
    1
    2
    Warning: multi-selection listbox control requires that Value be an integer within String range
    Control will not be rendered until all of its parameter values are valid
    et voici le code que j'ai écrit dans le callback de ce bouton :

    Code : Sélectionner tout - Visualiser dans une fenêtre à part
    1
    2
    3
    4
    5
    6
    7
     
    function change_Callback(hObject, eventdata, handles)
    selected=get(handles.listbox1,'value');
    for i =1 :length(selected)
        set(handles.listbox1,'string','x','value',selected(i));
    end
    guidata(hObject,handles);
    le guide parait comme ça :

    http://www.4shared.com/photo/7fBIg-GA/Untitled.html

    c'est une image qui peut s'ouvrir dans le software " paint"

    quelques aides s'il vous plait
    cette fois je suis préssé .
    merci en avance

    ce qui me gêne beaucoup , et je m'oblige de refaire le projet de nouveau après 8 heures de travail continu car le guide ne s'ouvre plus

    et bien , qu'est ce que je fais ??

    Bonsoir
    1)y-a-t'il une fonction qui permet de faire stop de l'éxécution du guide tout en gardant le fenêtre du guide ouverte ?

    2) après recherche ,j'ai trouvé une fonction qui permet de faire delete pour un file d'extension (.m) déjà éxistant
    La fonction est : delete(filename);

    y-a-t'il une fonction qui permet de créer un nouveau file (.m) et le mettre dans un répertoire que je spécifie ??

    ex:

    Code : Sélectionner tout - Visualiser dans une fenêtre à part
     Create('C:\mydocuments\matlab\new_mfile');
    je sais que la fonction Create n'existe pas pour cette tache
    mais pour vous approcher l'idée
    Remarque: j'ai très besoin de cette fonction dans mon application .

    mes meilleurs regards
