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