Popup menu - fedkor - 04-02-2016 15:12
Zdravím, v GUI matlabu dělám aplikaci převodu jednotek. Pomocí pop menu1 vybírám jednotky mezi mW,W,kW,MW a pomocí pop menu2 s,ms,us,ns,ps,fs. Při výběru danné jednotky například mW se mi do proměnné x uloží hodnota 1000 a při výběru ns se uloží y=1000000000. Těmato proměnnýma bych pak chtěl vynásobit v rovnici
energie = (x * handles.metricdata.vykon) * (y * handles.metricdata.sirkapulsu);
čísla zadané uživatel(vykon,sirkapulsu) a pak dostat výsledek, nějak mi to ale nechce fungovat.
Nevíte někdo prosím co s tím ? V příloze zasílám i fotku aplikace.
Děkuji moc
Zasílám celý kód aplikace:
function varargout = prazdne(varargin)
% PRAZDNE MATLAB code for prazdne.fig
% PRAZDNE, by itself, creates a new PRAZDNE or raises the existing
% singleton*.
%
% H = PRAZDNE returns the handle to a new PRAZDNE or the handle to
% the existing singleton*.
%
% PRAZDNE('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in PRAZDNE.M with the given input arguments.
%
% PRAZDNE('Property','Value',...) creates a new PRAZDNE or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before prazdne_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to prazdne_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

Zdravim
Ak to nie je tajne hodil by sa aj subor prazdne.fig...
Vopred vdaka
