[Help-gsl] Random vectors

[Éric Germaneau]

Dear all,

I wonder how to generate random vectors with  GSL.
I'm aware of the *gsl_ran_dir_nd *routine but the numbers are normalized.
I need to generate random velocities for a given temperature of N particles.
I currently call *gsl_ran_gaussian* 3N times.
That's too expensive.
I'd like to generate a 3N vector at once.
Is there anyway to do this with GSL?

Thanks,

                  Éric.
