- /*
- C++ functions for MT19937, with initialization improved 2002/2/10.
- Coded by Takuji Nishimura and Makoto Matsumoto.
- This is a faster version by taking Shawn Cokus's optimization,
- Matthe Bellew's simplification, Isaku Wada's real version.
-
- Before using, initialize the state by using init_genrand(seed)
- or init_by_array(init_key, key_length).
