一般可以直接使用latex code title(‘\lambda’) 但是有些函数不能用，比如\sqrt{}。可以这么解决： title('$\sqrt{f}$','Interpreter','latex') 有些地方直接不能用，比如legend，但是可以这么解决 legend({'$\lambda$'},'Interpreter','latex') tick上不能用，用format_ticks()函数 format_ticks(gca,{x轴上放的东西}，{y轴上放的东西}，{x轴的哪些位置上放东西},{y轴的哪些位置上放东西},旋转文字角度x轴,旋转文字角度y轴,文字离轴距离,性质,参数)。 可选参数，旋转文字角度x轴,旋转文字角度y轴,文字离轴距离, 缺省全部是0。 性质和参数可选，常用的都可以用。比如’FontSize’,100（大了点儿哈。。。） y轴上放的东西的格式为{’$a$’,’$b$’……}，这里的$必不可少。 可以只改x轴，只改y轴的时候x轴有变化，暂时不知道怎么解决。 重新修改了下程序，好像是解决了，不知道对不对。 format_ticks(gca,{}, {y轴上放的东西}, ) 在需要的时候可能会用到字符串加数字的组合，比如 for i = 1:10 figure plot(s(i,:)) title( ) end 如何将latex也加入其中: title( ,'Interpreter','latex','FontSize',25) %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %% BEGIN HEADER %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %Name: format_tick.m % %Usage: = ... % format_tick(h,tickx,ticky,tickposx,tickposy,rotx,roty,offset,... % varargin);
