%read the two images
I1=imread('43.png');
I1=imresize(I1,0.5);
I1=rgb2gray(I1);
I2=imread('60.png');
I2=imresize(I2,0.5);
I2=rgb2gray(I2);

%find SURF features
points1=detectSURFFeatures(I1);
points2=detectSURFFeatures(I2);

%extract the features
[f1,vpts1]=extractFeatures(I1,points1);
[f2,vpts2]=extractFeatures(I2,points2);

%matches
indexPairs=matchFeatures(f1,f2,'Prenormalized',true);
matched_pts1=vpts1(indexPairs(:,1));
matched_pts2=vpts2(indexPairs(:,2));

%display the matched results
figure('name','result');
showMatchedFeatures(I1,I2,matched_pts1,matched_pts2);
legend('matched points 1','matched points 2');
现在想把生成的matched_pts1里location中的数据输出到一个TXT中，怎么做?求大神帮忙啊！

用xlswrite('a.xls',a)命令不会当一维数组处理的,存完后是2行3列的,你再试试看
