Matlab设置坐标轴穿过原点

 ax1.YAxisLocation = 'origin';

    
 ax1.XAxisLocation = 'origin';
    
 %%%%%%或者
    
 set(gca,'YAxisLocation','origin');
    
 set(gca,'XAxisLocation','origin');
    
    
    
    

 clc;

    
 clear;
    
 close all;
    
 f1 = figure(1);
    
 ax1 = axes(f1);
    
 ax1.YAxisLocation = 'origin';
    
 ax1.XAxisLocation = 'origin';
    
 axis([-4,5,-4,5]);
