matlab实习卷积运算。很高兴与大家分享此代码。

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