Detailed Description

Random number generator base on M-series.

This class generates the M-series random numbers. The original version in Fortran was written by J.Makino and O.Miyamura (Ver.3.0 21 July 1991). Public version is available under GNU GPL: Shinji Hioki, QCDMPI http://insam.sci.hiroshima-u.ac.jp/QCDMPI/ which implements Jun Makino, "Lagged-Fibonacci random number generators on parallel computers", Parallel Computing, 20 (1994) 1357-1367.

An instance is created with a given integer number which is used to set the initial random numbers. [23 Jul 2012 H.Matsufuru]
