i have 40 images i extract the surf features 10 strongest points in a loop but the variable where i stored the values, it gives me the values of last image i.e. 10x2 values. i want to save the values for all 40 images in that single variable.how can i get for all images?? for 40 images my desired result is 40x 2. any help will be really appreciated.thanks

this is my code

srcFiles = dir('mypath\*.jpg');
for i = 1 : length(srcFiles)
        filename = strcat('mypath',srcFiles(i).name);
        input_images = imread(filename);
        I2=rgb2gray(input_images);
        points1 = detectSURFFeatures(input_images)
        strongest = points1.selectStrongest(10);
        %  
        plot(strongest);
        strong= round(strongest.Location);
end

Just use a cell array and indexing:

D = 'mypath';
S = dir(fullfile(D,'*.jpg'));
N = numel(S);
C = cell(1,N);
for kk = 1:N
    filename = fullfile(D,S(kk).name);
    ...
    strongest = points1.selectStrongest(10);
    C{kk} = strongest;    
end
