均值滤波,加权滤波,中值滤波的MATLAB实例,用于图象及信号的处理

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