f2.m

matlab在图形处理方面的简单应用 matlab简单程序设计

function varargout = f2(varargin)
% F2 M-file for f2.fig
%      F2, by itself, creates a new F2 or raises the existing
%      singleton*.
%
%      H = F2 returns the handle to a new F2 or the handle to
%      the existing singleton*.
%
%      F2('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in F2.M with the given input arguments.
%
%      F2('Property','Value',...) creates a new F2 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before f2_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to f2_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
