Re: [Help-gsl] Random number generation

[dantian]

Hi,

here is how I initialized  my random number generator (I use taus but 
you can adapt it for your case).

- First in the code:

*  const gsl_rng_type *Type_rdm ;
  gsl_rng *alloc_rdm ;
  gsl_rng_env_setup() ;
  Type_rdm = gsl_rng_default ;
  alloc_rdm = gsl_rng_alloc (Type_rdm) ;*

/(It's actually from gsl website)/

- Then before execute the program I do:

  *setenv GSL_RNG_TYPE taus
  setenv GSL_RNG_SEED `date +%s`*

/(Also from gsl website)/

It do work pretty well.

Hope it helps,
Best,

          Eric.
