multiline LaTeX code

I'm trying to add some more complex LaTeX-rendered equations into a a
figure, and having some problems. I've been trying various things
with 'usetex', but it seems the problem might be that I can't seem to
write the LaTex code on a single line.

For example, can you not do:
ax.text(0,0,r"""
...
...
""")

?

One example that I'm trying is the following, using 'cases'. I'll
paste a complete .tex file:

\documentclass{article}
\pagestyle{empty}
\usepackage{amsmath}
\begin{document}

\begin{equation*}
x(t) =
\begin{cases}
1, \quad & t \ge 0 \\
0, & t < 0
\end{cases}
\end{equation*}

\end{document}

Any suggestions? I think this works with '\displaystyle' inside
single '$', but you need multiple lines... ?

thanks,
Ken

Hi Ken,

I’m sorry, multi-line
input is currently not supported. I’ve got a lot of other projects on
my plate and dont intend to implement such a feature myself, but I’d
have a look at a patch if one were submitted that wasn’t too invasive.
The usetex stuff was pretty hairy to get working across platforms, so
I’m reluctant to mess with it.
