André,
the new parser is very good! I notice, however, that entries like x' seems to
get translated to x{backward-facing epsilon}.
Here's the equation.
Angus
\begin{center}\[
\left(\begin{array}{c}
x\\
y\\
z\end{array}
\right)=\left(\begin{array}{c}
x_{4} \\
y_{4} \\
z_{4} \end{array}
\right)+\left(\begin{array}{ccc}
\left(x_{1} -x_{4} \right)\left(x_{2} -x_{4} \right)\left(x_{3} -x_{4}
\right)\left(y_{1} -y_{4} \right) & \left(y_{2} -y_{4} \right) & \left(y_{3}
-y_{4} \right)\\
\left(z_{1} -z_{4} \right) & \left(z_{2} -z_{4} \right) & \left(z_{3} -z_{4}
\right)\end{array}
\right)\left(\begin{array}{c}
x'\\
y'\\
z'\end{array}
\right)\]
\end{center}
