Re: [Help-gsl] random number generator

[David Schaich]

Hi Amy,

Try this:

const gsl_rng * r = gsl_rng_alloc(gsl_rng_mt19937) ;
gsl_rng_set(r, s);

Right now that will use the Mersenne Twister generator.  You can change 
the argument of gsl_rng_alloc to use the generator of your choice.  
There's a list of available generators at
