Ich möchte nun in einer Extra funktion diese Variablen mit den zugehörigen Werten in einem ASCII File Speichern.
Mein Problem ist jetzt in meiner weiteren Funktion an die Werte und Variablen der vorangegangenen Funktionen ranzukommen.
Hat Jemand eine Idee wie das am besten gelöst werden könnte?

Titel: Re: Variablen aus Funktion auslesen
Hallo morisq,
Du könntest die Variablen doch einfach als Inpzut für die folgende Funktion verwenden. Wenn Dir das wegen einer großen Zahl an Variablen zu uinübersichtlich wird, packe sie einfach in ein STRUCT.
initialisieren?
oder ausserhalb?
Ich muss evtl dazuschreiben das ich ein GUI programmiere und da nicht so recht weiß an welche stelle ich globale variablendeklarationen setzen soll.
Hallo Jan, das klingt gut, aber ich weiß nicht so recht wie ich dei Variablen als input für meine folgende Funktion verwenden kann. Hättest du ein kleines Beispiel in Codeform?
MfG
Ich glaube ich poste am besten mal mein Programm bisher. Es soll einen elementaren Taschenrechner darstellen der + - * / rechnet.
Ich möchte in einer extra Funktion die zwischenwerte wie a_sum,b_sum etc. in ein ASCII File speichern. Hier mein Code:
Code:
functionvarargout = BasicCalculator(varargin) % BASICCALCULATOR M-file for BasicCalculator.fig % BASICCALCULATOR, by itself, creates a new BASICCALCULATOR or raises the existing % singleton*.
%
% H = BASICCALCULATOR returns the handle to a new BASICCALCULATOR or the handle to % the existing singleton*.
%
% BASICCALCULATOR('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in BASICCALCULATOR.M with the given input arguments.
%
% BASICCALCULATOR('Property','Value',...) creates a new BASICCALCULATOR or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before BasicCalculator_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to BasicCalculator_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one % instance to run (singleton)".

ok, ich habs gelöst, über die handles kann ich innerhalb einer funktion meine Variablen weitergeben und in neue funktionen übernehmen.
Danke euch trotzdem für die Hilfe.
