filterfig.asv

用matlab的GUI做的一个数字信号处理系统

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