function varargout = ps(varargin)% PS M-file for ps.fig% PS, by itself, creates axes1 new PS or raises the existing% singleton*.%% H = PS returns the handle to axes1 new PS or the handle to% the existing singleton*.%% PS('CALLBACK',hObject,eventData,handles,...) calls the local% function named CALLBACK in PS.M with the given input arguments.%% PS('Property','Value',...) creates axes1 new PS or raises the% existing singleton*. Starting from the left, property value pairs are % applied to the GUI before ps_OpeningFcn gets called. An% unrecognized property name or invalid value makes property application % stop.
