Matlab坐标轴Latex标注

matlab的xlabel和ylabel可以用Tex/Latex标注,但是坐标刻度不行,下面的函数可以使用Latex或者Tex方式来标注坐标轴,使用text来替代原来的坐标轴刻度文字.

函数

function ht = my_xticklabels(varargin)

% ht = my_xticklabels(Ha, xtickpos, xtickstring)
% or
% ht = my_xticklabels(xtickpos, xtickstring)

textopts = {};
if length(varargin{1})==1 && ...
        ishandle(varargin{1}) && ...
        strcmpi(get(varargin{1},'Type'),'axes');
    Ha = varargin{1};
    xtickpos = varargin{2};
    xtickstring = varargin{3};
    if nargin > 3
        textopts = varargin(4:end);
    end
else
    Ha = gca;
    Hfig = get(Ha,'Parent');
    xtickpos = varargin{1};
    xtickstring = varargin{2};
    if nargin > 2
        textopts = varargin(3:end);
    end
end

set(Ha,'XTick',xtickpos, 'XTickLabel','')
h_olds = findobj(Ha, 'Tag', 'MUXTL');
if ~isempty(h_olds)
    delete(h_olds)
end

% Make XTickLabels
NTick = length(xtickpos);
Ybot = min(get(gca,'YLim'))-0.12;
ht = zeros(NTick,1);
for ii = 1:NTick
    ht(ii) = text('String',xtickstring{ii}, ...
        'Units','data', ...
        'VerticalAlignment', 'top', ...
        'HorizontalAlignment', 'center ', ...
        'Position',[xtickpos(ii) Ybot], ...
        'Tag','MUXTL', ...
        'Interpreter','LaTex');
end
if ~isempty(textopts)
    set(ht,textopts{:})
end

% squeeze axis if needed

set(Ha,'Units','pixels')
Axpos = get(Ha,'Position');
% set(Hfig,'Units','pixels')
% Figpos = get(Hfig,'Position');

set(ht,'Units','pixels')
TickExt = zeros(NTick,4);
for ii = 1:NTick
    TickExt(ii,:) = get(ht(ii),'Extent');
end

needmove = -(Axpos(2) + min(TickExt(:,2)));

if needmove>0;
    Axpos(2) = Axpos(2)+needmove+2;
    Axpos(4) = Axpos(4)-needmove+2;
    set(Ha,'Position',Axpos);
end

set(Ha,'Units','normalized')
set(ht,'Units','normalized') 

end

调用测试:

figure(4);
subplot(3,1,1); 
b = bar(1:10);
grid on;
xtl_text = {'$X_{\mu}$', '$X_{\mu\mu}$', '$X_{\mu\mu\mu}$', '$X_{vv}$', '$X_{rr}$', '$X_{rv}$', '$X_{\delta\delta}$', '$X_{\mu\delta\delta}$', '$X_{v\delta}$', '$X_{{\mu}v{\delta}}$'};
xtk = get(gca,'xtick');
h = my_xticklabels(gca,xtk,xtl_text);
