大家好，我是讯享网，很高兴认识大家。这里提供最前沿的Ai技术和互联网信息。

用subplot，imshow，imread，遍历并显示图库文件夹中的人脸图像（用循环）。运行后图像要显示成矩阵模式的，还得产生统一矩阵和均值矩阵。大侠们帮帮小妹吧，自己编的最好，如果从网上扒的最好能有简单的注解！

clc clear all close all clear memory nump=40; %no_of_classes nots=5; %no_of_training_set D=pwd; cd([D, ‘ORLDatabase’]); [face,MAP]=imread(‘face1.bmp’); [a,b]=size(face); counter=0; for i=1:nump

for j=1:nots file=['face' int2str((i-1)*10+j) '.bmp']; [face,MAP]=imread(file); grayface=ind2gray(face,MAP); counter=counter+1; X(counter,:)=double(reshape(grayface,a*b,1)); end

end counter=0; for i=1:nump

for j=nots+1:10 file=['face' int2str((i-1)*10+j) '.bmp']; [face,MAP]=imread(file); grayface=ind2gray(face,MAP); counter=counter+1; Y(counter,:)=double(reshape(grayface,a*b,1)); end
