Of course the multivariate normal.

To be concrete i have to calculate the dens

I presume that you want the density of a multivar normal distrib. You
don't calculate the inverse; you just need the quadratic form. I think
that Searle's matrix algebra book gives
Hi!
I wonder how the public is evaluating the normal distribution function
in realworld applications. I am implementing some methods where i have
to calculate different times probability functions relying on normal
distribution functions with steadily changing covariance matrix and mean
values.
