PCA算法实现人脸识别（基于matlab GUI界面）

function varargout = FaceRecognitionDemo(varargin) % FACERECOGNITIONDEMO M-file for FaceRecognitionDemo.fig % FACERECOGNITIONDEMO, by itself, creates a new FACERECOGNITIONDEMO or raises the existing % singleton*. % % H = FACERECOGNITIONDEMO returns the handle to a new FACERECOGNITIONDEMO or the handle to % the existing singleton*. % % FACERECOGNITIONDEMO('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in FACERECOGNITIONDEMO.M with the given input arguments. % % FACERECOGNITIONDEMO('Property','Value',...) creates a new FACERECOGNITIONDEMO or raises the % existing singleton*.
