rand_gauss


This routine returns a number out of a pseudo-random normal deviate (ie, its probability distribution is a Gaussian of mean 0 and variance 1).

FORMAT

var=rand_gauss( rng_handle )


ARGUMENTS

name & dimensionality kind in/out description
       
rng_handle planck_rng INOUT structure of type planck_rng containing on all information necessary to continue same random sequence.
var DP OUT number belonging to a pseudo-random normal deviate.


EXAMPLE:

use healpix_types
use rngmod
type(planck_rng) :: rng_handle
real(dp) :: gauss

call rand_init(rng_handle, 12345, 6789012)
gauss = rand_gauss(rng_handle)
initiates a random sequence with the pair of seeds (12345, 6789012), and generates one number out of the normal deviate.
