[ODE] dInvertPDMatrix

I'm currently trying to understand what  dInvertPDMatrix actually does.
Does it anything else than the cholesky decomposition of the matrix I
and writing the result in the inverse I matrix?

(sry, it's German , but includes pseudo-Code not available in the  
English one)
explains howto do it.

Does the pseudo-code and the example are equivalent to what  
dInvertPDMatrix does?
It would be very cool if someone could write me an example I matrix  
with resulting inverse-I matrix, so I can take the code from  
Wikipedia and get it to do the same thing.

	big thx,
