When using latex interpreter for text(...) the minus sign vanishes in superscript and in \frac{}. I tried linking my latex base folder to matlab but this has not solved the problem.

I don't have this problem with Debian 6 running R2012a

Remember the Linux font problems of R2010a-ish. Some of those were tracked down to some versions of Linux not installing all the necessary fonts; and some of the problems were tracked to the default X library having improper optimizations; and some of the problems I did not hear the cause of.

This seems too long for a comment, but it is not really an answer either ...
I am pretty sure MATLAB uses its own LaTeX engine and does not generally make use of any installed versions of LaTeX (similar to how MATLAB deals with JAVA).
If I recall the days before export_fig when I was using Windows, exporting figures to .ai/eps/pdf files and importing them to Illustrator used to cause the minus sign to disappear.
What renderer are you using?
Can you post example code so we can try and reproduce the problem?

I am running R2008a. I use ubuntu 10.04 and haven't changed any library there, so i don't really know which library I am using.
A running example is:
x=0:10;
y=0.5*x;
plot(x,y);
text(1,4,'$\exp{-x^2}$ or $x^{-2}$','interpreter','latex');
print -depsc test.eps
In the matlab figure the minus vanishes, whereas in the eps the x^2 and 2 are printed on the minus. The minus takes somehow no space.
