如何在Matlab图形的数据光标中添加希腊字母? [英] How to add Greek letter to data cursor in Matlab figure?

问题描述

我在Matlab图形中添加了一个数据游标，这是单击编辑文本更新功能..."时显示的代码.

I added a data cursor in a Matlab figure, and this it the code shown when I clicked "Edit Text Update Function..."

function output_txt = myfunction(obj,event_obj)
% Display the position of the data cursor
% obj          Currently not used (empty)
% event_obj    Handle to event object
% output_txt   Data cursor text string (string or cell array of strings).

pos = get(event_obj,'Position');
output_txt = {['X: ',num2str(pos(1),4)],...
    ['Y: ',num2str(pos(2),4)]};
% If there is a Z-coordinate in the position, display it as well
if length(pos) > 2
    output_txt{end+1} = ['Z: ',num2str(pos(3),4)];
end

我在这里要做的是用希腊字母(例如"alpha"或"beta")替换字符"X"，"Y".我该怎么办?

What I want to do here is replacing the characters 'X', 'Y' by the Greek character like 'alpha' or 'beta'. How can I do that?

谢谢！

推荐答案

\ alpha(和某些LaTeX符号)在标题中起作用，在这种情况下也可能起作用. 注意:\ Alpha是大写希腊字母，\ alpha是小写字母.

\alpha (and some LaTeX symbols) works in title and probably in this case too. Note: \Alpha is the capital greek letter, \alpha is the small one.

请参见此表.
