GUI pushbutton to stop

Hi everyone

I can't creat a Pushbutton that's stop my GUI without closing everything.

In the final program some parameter will be set, program will be run, and stoped if some parameters need to be changd, and run again.

As you can see, the stopButton only give me the Disp, but doesn't stop

function GUI_Code
clc
clear all
close all
% f=figure('units','normalized','outerposition',[0 0 1 1]);
% f=figure('WindowState','fullscreen');
f_tot=figure;

% set(f_tot, 'MenuBar', 'none');
set(f_tot, 'ToolBar', 'none');

sz=get(0,'screensize');
set(gcf,'position',[1 sz(1,4)/20 sz(1,3)/1. sz(1,4)/1.1]);
set(gcf,'Color',[0.15 0.15 0.15]);
