Hi,
I was wondering if there's any way to plot/visualize a metric (mostly the spatial part). I want to see how the robertson-walker metric differs from a rotating rw-metric;
\begin{align}
ds^2=-(1-\omega^2a^2r^2\sin^2\theta)dt^2+a^2[\frac{dr^2}{1-kr^2}+r^2d\theta^2+r^2\sin^2\theta d\phi^2]-2\omega a^2 r^2\sin^2\theta d\phi dt.
\end{align}
Does anyone know if it can be done in MATLAB or maple (and how)?
