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