NAME

Math/Random/mt19937ar.pir - the Mersenne Twisted pseudorandom number generator

DESCRIPTION

This is a PIR version of the C-program for MT19937.

The MT19937 algorithm was created by Makoto Matsumoto and Takuji Nishimura.

See http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/emt.html and http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/MT2002/emt19937ar.html.

Initialization

init_genrand (seed)

initializes the state vector by using one "seed", which may be zero.

init_by_array (init_key)

initializes the state vector by using an array.

Generation

After initialization, the following type of pseudorandom numbers are available.

genrand_int32 ()

generates a random number on [0,0xffffffff]-interval

genrand_int31 ()

generates a random number on [0,0x7fffffff]-interval

genrand_real1 ()

generates a random number on [0,1]-real-interval

genrand_real2 ()

generates a random number on [0,1)-real-interval

genrand_real3 ()

generates a random number on (0,1)-real-interval

genrand_res53 ()

generates a random number on [0,1) with 53-bit resolution
