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