objects={'apple','bat','beetle'}; trimgs=10;
for i=1:length(objects) for j=1:trimgs imgpath=['.\images\' objects{i} '\img (' int2str(j) ').gif'];
I=imread(imgpath);
J = imresize(I,[256,256]);
fid=fopen('feature_vector.txt','a');
fprintf(fid,'%i\t',hog_feature_vector(J));
fprintf(fid,'\n');
fclose(fid);
end
end
%this code print feature vector in the text file. but not matrix form.

hog_feature_vector is a 1-d vector. How do you want it to be in a matrix? Like, how many rows and columns, and why?
