The code is not readable. Please use the "{} Code" button to format it.

clc; clear all; close all; warning off; is a really brute header. It is waste of time to remove all loaded functions from the memory by clear all and counterproductive to disable all warnings: Fix the reasons of warnings instead of ignoring the messages.
