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).
Location in HEALPix directory tree:
src/f90/mod/rngmod.f90
FORMAT var=rand_gauss(

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.
