recuperer les valeures edit text

**alinee** · 12/07/2014, 01h03

bon soir à tous;
s'il vous plait vous pouvez m'aider concernant le développement d'une interface graphique sous matlab.
j'ai une interface contient un ensemble de edit text pour entrer un ensemble de paramètres puis cliquer sur Ok pour avoir un tracé en fonction de ces paramètres. le programme de ce tracé est déja existe sous forme '...' .m , dans ce programme j'ai utilisé des variable x,y,z la valeurs de ces variable je veux les récupérer depuis les edit texte selon les choix de l'utilisateur. la problème c'est que je sais pas comment récupérer ces variable depuis les edit text
j'espere que jé reusi à exprime mon problème

merci d'avance

Bonjour,

L'accès se fait à l'aide de la propriété 'String' :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

contenu = get(handles.ton_edit, 'String');

qui donne la chaine de caractères saisie, et pour obtenir la valeur numérique, on applique str2double dessus (ou str2num s'il y a plusieurs valeurs).

merci pour la réponse,
mais j'ai essayé ça et dans le callback du mon push button et ça marche pas

voila mon interface :
et voila mon programme que je veux l'exécuter lorsque j’appuie sur OK

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

h11=h1*lamda;
h22=h2*lamda;
r1=d*lamda/2;
ol=atan(h1/r1);
a=0:pi/180:ol;
x=abs(cos(a).*sin(2*pi*(h1+h2)*sin(a)/lamda));
polar(a,x)
hold on
 
a=ol:pi/180:pi/2;
y=abs(cos(a).*sin(2*pi*h1*sin(a)/lamda));
polar(a,y)

avec les variables que je veux récupérer depuis mon interface sont: h1, h2,d et lamda

Envoyé par alinee

mais j'ai essayé ça et dans le callback du mon push button et ça marche pas

Qu'as-tu essayé précisément ? « Ça marche pas » = une erreur ? Si oui laquelle ?

j'ai essayé cette solution la mais ça marche pas : http://www.developpez.net/forums/d10...ration-string/
s'il vous plait j'ai besoin de vos aides

oui une erreur quand je tapes les paramètre et je clique voilà le résultat

??? Undefined function or variable 'h10'.

Error in ==> essa at 3
h11=h10*lamda;
 
??? Error while evaluating uicontrol Callback

voila mon code de l'interface

où essa c'est le nom de mon programme de calcul

**alinee** · 14/07/2014, 16h41

Merci pour ton aide;
il est résolu; la solution c'est comme suite:
le programme de calcul je le rends comme une fonction de variable d’entrée(variables1,2,...)
après dans le code de mon interface j'ai écris dans le callback de mon bouton OK

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

variable1=str2double(get(handles.mon-edit,'String'));

après j'ai appelé mon fonction de calcul par mon-fonction(variable1,2...)
