detreeexp1.m

具有图形操作界面的支持向量机多类分类实验系统.全部用Matlab实现,可以实现多种分类识别. 这是本人的毕业设计的附属程序

function varargout = DetreeExp1(varargin)
% DETREEEXP1 M-file for DetreeExp1.fig
%      DETREEEXP1, by itself, creates a new DETREEEXP1 or raises the existing
%      singleton*.
%
%      H = DETREEEXP1 returns the handle to a new DETREEEXP1 or the handle to
%      the existing singleton*.
%
%      DETREEEXP1('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in DETREEEXP1.M with the given input arguments.
%
%      DETREEEXP1('Property','Value',...) creates a new DETREEEXP1 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before DetreeExp1_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to DetreeExp1_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
