Dear all,

I am working with a likelihood function that requires the inverse of many small covariance matrices for multivariate normal densities. When the sample size is large, this calculation is really heavy. Those matrices are independent but unfortunately I can hardly find a way to vectorize them.

Can anyone give me a hint to speed this up? Thanks in advance!
