Hi,(adsbygoogle = window.adsbygoogle || []).push({});

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)?
