◆ _init_genrand()

void _init_genrand ( unsigned long s )

Initialization with seed for random number generator (Mersenne Twister)

Purpose: Initializes the Mersenne Twister (MT19937) random number generator with the seed.
The random number generator should be initialized by init_genrand() or init_by_array() before generating random numbers.

Parameters

[in] s Seed. (unsigned 32-bit integer which may be zero.)

Note: If the random number generator is called without an initialization by init_genrand() or init_by_array(), it will be automatically initialized by using 5489 as the seed.
