Verfasst am: 11.11.2008, 16:16 Titel: gui+plot

hallo leute, gleich mit dem ersten beitrag bin ich lästig. Smile

folgendes m-file für ein gui läuft nicht wie ich es möchte.

die fehlermeldung lautet:

??? In an assignment A(I) = B, the number of elements in B and
I must be the same.

Error in ==> string1>refresh_Callback at 434
x(2) = va*dt + x(1);

Code:

function varargout = string1(varargin)
% STRING1 M-file for string1.fig
% STRING1, by itself, creates a new STRING1 or raises the existing
% singleton*.
%
% H = STRING1 returns the handle to a new STRING1 or the handle to
% the existing singleton*.
%
% STRING1('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in STRING1.M with the given input arguments.
%
% STRING1('Property','Value',...) creates a new STRING1 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before string1_OpeningFunction gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to string1_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
%
% See also: GUIDE, GUIDATA, GUIHANDLES

Hallo,

Code:

va = get(handles.v0,'string')/3.6; %in m/s

Funktion ohne Link?

Du musst den String erst wieder in eine Zahl umwandeln (z.B. mit "str2double"), ansonsten nimmt er glaub ich die ASCII-Werte eines jeden einzelnen Zeichens her (so ergibt '34'/1 -> 51 52). Den Rest habe ich mir noch nicht angesehen, aber die Fehlermeldung kommt daher, dass dir deine Gleichung "x(2) = ...." nicht ein Skalar, sondern ein Array zurückliefert - und du versuchst dies in ein Skalar zu schreiben - was natürlich nicht geht.

Achja, versuch bitte beim nächsten Mal nicht den ganzen Source-Code, sondern nur den relevanten Teil (Minimalbeispiel) zu posten.

MfG
