I am creating a function that will let the user give a directory name and file type, and then the function will take those and search for the corrosponding files

Use dir:

and fullfile:

Either loop over each of the file extensions and call dir for each one, or call dir on the folder and then filter for the extensions that you want to keep (you might find fileparts useful for this).
