TeX string incomplete?!

[Armin Mueller]

Hello all,

here is a small program that will issue a warning in R2008b. I don't
understand why, because I chose 'none' as 'Interpreter'.

Warning: incomplete command in TeX text string:
'Luft40ms_D40_25mm2s_Sirene_250Hz_'
> In legendcolorbarlayout>doLayoutCB at 283
In title at 46
In title at 23
In title_bug at 15

The isolated code line is running without warning:

>> title('Luft40ms_D40_25mm2s_Sirene_250Hz_', 'Interpreter', 'none')

Where is the difference? Any hints?

Thanks!
Armin

plot(1:2);
legend('error');
title(s,'interpreter','none');
%{

The source of the problem is the '_' sign in the string which you put in your title. I had the same problem (so I got here), and solved it by discarding the _ from the string.
If you want to use the underscore, you should probably use the TeX command \textunderscore for it (http://www.tex.ac.uk/cgi-bin/texfaq2html?label=underscore)
I'm not sure how exactly to use TeX in plots, but it should be explained here: http://www.mathworks.nl/help/matlab/ref/texlabel.html
