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

i keep getting a compiling error message for the gsl function:

gsl_rng_set(const gsl_rng * r, s);

which is inside a for loop

the error message is:

visit.c: In function `main':
visit.c:27: parse error before `const'

[which is related to that function above]
