How can I insert proper tex interpreter inside figures?

When I try to add greater or equal sign to my figure, it is shown as '?'. To my surprise most of the tex symbols are not properly displayed.

I have tried the following, but none has worked so far:

• add all MATLAB fonts to FontBook (OS X)
• specifically switching interpreter to tex

When I use latex as my interpreter, however, it appears properly. But I can't control fontname properties to match other texts on the figure.

Any ideas what is going on here?

My MATLAB version is R2012a and OS X 10.8.2.

Please post some example code.

text(1,1,'x \geq y','interpreter','tex')

What version of Matlab do you have? If you save your figure as eps, does the interrogation sign appear in the image?

My Matlab version is R2012a.

There is no problem when I save figures as pdf or eps (*). I suspect there is a problem with the fonts installed on X11.

(*) edit: interrogation sign appears properly when I save in these two formats.

You could check if you have Tex Computer Modern in Fontbook. If they are not in your system, that could be the problem.

While my guess is that their is probably a much simpler solution (like install the correct fonts). The TeX interpreter is fully configurable (although poorly documented). See this question.
