Are there Any Restrictions on Latex Markup in Figure Titles?

This works fine:
syms t
s1(t) = exp(-abs(t));
But this does not
s2(t) = piecewise(t<-1,0, t>2,0, exp(-abs(t)));
Warning: Error updating Text.

String scalar or character vector must have valid interpreter syntax:
$\left\{\begin{array}{cl} 0 & \text{\ if\ \ }t<-1\vee 2<t\\ {\mathrm{e}}^{-\left|t\right|} & \mathrm{ otherwise} \end{array}\right.$
Is there any way to get s2(t) on the figure in any way at all (title, text, anything)?

The Symbolic Math Toolbox has its own way of depicting piecewise functions:
syms t
s2(t) = piecewise(t<-1,0, t>2,0, exp(-abs(t)))
s2(t) = 
I doubt that could be incorporated into a text object of any sort.

The \text is the immediate problem. If you use \textrm instead then you get something

\text is part of the amsmath package. There is no documentation as to which packages the various components support, but amsmath is decidedly not supported for graphics objects.
