You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: aas_findfiles.m
    path of file: ./repos/automaticanalysis/aa_engine
    
    the code of the file until where you have to start completion: %function [aap,resp]=aas_findfiles(aap,searchpath,minfiles,maxfiles)
% if minfiles is not specified it defaults to 1
% if maxfiles is not specified it defaults to minfiles
% checks a directory is made - if not makes it
