|
|
A C-program for MT19937-64 (2004/9/29 version).
|
||
|
|
Coded by Takuji Nishimura and Makoto Matsumoto.
|
||
|
|
|
||
|
|
This is a 64-bit version of Mersenne Twister pseudorandom number
|
||
|
|
generator.
|
||
|
|
|
||
|
|
Before using, initialize the state by using init_genrand64(seed)
|
||
|
|
or init_by_array64(init_key, key_length).
