ticklabel中可否插入Latex公式？

凌绝顶

比如xticklabel为 X_1， X_2，。。。即X加数字下标。如果可以，怎么操作？谢谢

1. function ht = my_xticklabels(varargin)
   
2. 
   
3. %MY_XTICKLABELS replaces XTickLabels with "normal" texts
   
4. %   accepting multiline texts and TEX interpreting
   
5. %   and shrinks the axis to fit the texts in the window
   
6. %
   
7. %    ht = my_xticklabels(Ha, xtickpos, xtickstring)
   
8. % or
   
9. %    ht = my_xticklabels(xtickpos, xtickstring)
   
10. %
    
11. %  in:    xtickpos     XTick positions [N*1]
    
12. %        xtickstring   Strings to use as labels {N*1} cell of cells
    
13. %
    
14. % Examples:
    
15. % plot(randn(20,1))
    
16. % xtl = {{'one';'two';'three'} '\alpha' {'\beta';'\gamma'}};

Matlab图形中title、xlabel、ylabel、zlabel、textbox和legend等支持latex，xticklabel好像不行，可以用上面函数实现
