subplot绘图时问题请教

subplot绘图时如何对众多图表设置共同的横坐标以及纵坐标描述啊？

指的是xlabel和ylabel

应该是xlabel 里的ax不能是向量。代码在下面。
只能用循环批量设置了，eval 或者sprintf。

1. function hh = xlabel(varargin)
   
2. %XLABEL X-axis label.
   
3. %   XLABEL('text') adds text beside the X-axis on the current axis.
   
4. %
   
5. %   XLABEL('text','Property1',PropertyValue1,'Property2',PropertyValue2,...)
   
6. %   sets the values of the specified properties of the xlabel.
   
7. %
   
8. %   XLABEL(AX,...) adds the xlabel to the specified axes.
   
9. %
   
10. %   H = XLABEL(...) returns the handle to the text object used as the label.
    
11. %
    
12. %   See also YLABEL, ZLABEL, TITLE, TEXT.

15. 
    
16. narginchk(1,inf);
    
17. 
    
18. % if the input has an xlabel property which is a text object, use it to set
    
19. % the xlabel on.
    
20. [ax,args,nargs] = labelcheck('XLabel',varargin);
    
21. if isempty(ax)
    
22.     ax = gca;
    
23.     args = varargin;
    
24. end
    
25. 
    
26. if nargs > 1 && (rem(nargs-1,2) ~= 0)
    
27.   error(message('MATLAB:xlabel:InvalidNumberOfInputs'))
    
28. end
    
29. 
    
30. string = args{1};
    
31. if isempty(string), string=''; end;
    
32. pvpairs = args(2:end);
    
33. 
    
34. if isappdata(ax,'MWBYPASS_xlabel')
    
35.   h = mwbypass(ax,'MWBYPASS_xlabel',string,pvpairs{:});
    
36. 
    
37.   %---Standard behavior
    
38. else
    
39.     h = get(ax,'XLabel');
    
40.     set(h,'FontSizeMode','auto',...
    
41.         'FontUnitsMode','auto',...
    
42.         'FontWeight',get(ax,'FontWeight'),...
    
43.         'FontAngle',get(ax,'FontAngle'),...
    
44.         'FontName',get(ax,'FontName'));
    
45.     set(h, 'String', string, pvpairs{:});
    
46.    
    
47. end
    
48. 
    
49. if nargout > 0
    
50.   hh = h;
    
51. end

描述指的是啥啊？范围精度这些吗？

1. x1 = linspace(0,10,100);
   
2. y1 = sin(x1);
   
3. ax1 = subplot(2,1,1);
   
4. plot(ax1,x1,y1)
   
5. 
   
6. x2 = linspace(0,5,100);
   
7. y2 = sin(x2);
   
8. ax2 = subplot(2,1,2);
   
9. plot(ax2,x2,y2)
   
10. 
    
11. axis([ax1 ax2],[0 10 -1 1])
