function varargout = ChooseData(varargin) % CHOOSEDATA MATLAB code for ChooseData.fig % CHOOSEDATA, by itself, creates a new CHOOSEDATA or raises the existing % singleton*. % % H = CHOOSEDATA returns the handle to a new CHOOSEDATA or the handle to % the existing singleton*. % % CHOOSEDATA('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in CHOOSEDATA.M with the given input arguments. % % CHOOSEDATA('Property','Value',...) creates a new CHOOSEDATA or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before ChooseData_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to ChooseData_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu.
