recognition_rate = number_of_faces_recognized / number_of_faces_presented;

number_of_faces_recognized = 0;
number_of_faces_presented = 0;
for K = 1 : number_of_face_images
face_image = imread() of the K'th face image
was_it_recognized = try_to_recognize_face(face_image);
number_of_faces_presented = number_of_faces_presented + 1;
number_of_faces_recognized = number_of_faces_recognized + was_it_recognized;
end
recognition_rate = number_of_faces_recognized / number_of_faces_presented;

Sir, I am also having the same problem. I dont understand the line you wrote
face_image = imread() of the K'th face image
was_it_recognized = try_to_recognize_face(face_image);
