Subject: multivariate gaussian distribution
Date: Sat, 20 Dec 2003 11:10:00 -0000	[thread overview]
Message-ID: <20031219195249.GA20239@wow.arc.nasa.gov> (raw)

Hi,

I've written a few lines of code that implement a multivariate
gaussian distribution. The function takes the eigenvalues/vectors
decomposition of the covariance matrix as input, and outputs a
random vector. In dimension n, it proceeds to n gsl_ran_gaussian
calls, plus a blas level 2 product. It fits in the GSL framework.

I guess it may be useful to other GSL users. Should it be added
to the library ? I can provide the piece of code + doc + theoretical 
reference.

Regards,

Emmanuel
