In general there is not a difference in performance between the class-folder and single file approach. When using MATLAB classes of either style, you may perceive a "first-time" cost when you first use the class in a MATLAB session, because the class is loaded on demand. The first-time cost may differ slightly between styles depending on your class, but after the class is loaded, there is not a difference in performance of methods.
