Matlab --- multi picture display of coordinate axis

% Premise ：3 The picture to be displayed is in the directory where the script is located 
% function ： take 3 Pictures are displayed on the same axis 
% edition ：V1.0

% create a window 
hFig = figure('Name',' Coordinate axis multi picture display BY Xiaoyu V1.0',...
    'NumberTitle','off',...
    'Resize','off',...
    'Position',[0 0 800 400],...
    'ToolBar', 'none',...
    'visible', 'off');
% Move the window to the middle of the screen 
movegui(hFig, 'center');
% Create axes , Be careful Y The axis direction should be reversed 
hAxes = axes('Units','Normalized',...
    'Position',[0.05 0.05 .9 .9],...
    'NextPlot','add',...
    'Box','on',...
