How to extract SURF features from more than two images i.e. from a folder of facial images?

I had tried the basic SURF features extraction using steps from MATLAB documentation. It works on two images, now i want to extract surf features from more images i.e. a folder of image. And how to get extracted features??
Thank you..
I want to extract features from folder of facial images using SURF descriptor.I tried with the below code but I'm getting error " _Subscripted assignment dimension mismatch.
Error in t8 (line 11) [features(:,i), valid_points(:,i)] = extractFeatures(I1, points1);"

Regarding your new/edited question....
Just use normal debugging techniques, like assigning the outputs to variables:
[out1, out2] = extractFeatures(I1, points1);
Now, see if out1 has the same number of rows as features, and if out2 has the same number of rows as valid_points. Really, it's just standard debugging techniques.

In the middle of those loops over different files, place your code to do SURF.
