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