function varargout = baru05(varargin) % BARU05 M-file for baru05.fig

% BARU05, by itself, creates a new BARU05 or raises the existing

% singleton*. %

% H = BARU05 returns the handle to a new BARU05 or the handle to

% the existing singleton*. %

%

BARU05('CALLBACK',hObject,eventData,handles,...) calls the local

% function named CALLBACK in BARU05.M with the given input arguments.

%

% BARU05('Property','Value',...) creates a new BARU05 or raises the

% existing singleton*. Starting from the left, property value pairs are

% applied to the GUI before baru05_OpeningFcn gets called. An

% unrecognized property name or invalid value makes property application

% stop. All inputs are passed to baru05_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
