_init_zignorm_r() void _init_zignorm_r ( int  n ) Initialization for normal random number generator (Ziggurat method) (reverse communication version) Purpose Initializes the normal random number generator zignorm_r(). Parameters [in] n The number of rectangles used in Ziggurat method. n = 128 or 256 can be specified. (if other value is given, 256 will be assumed) Note init_zignorm() and init_zignorm_r() initialize the same rectangles shared by zignorm() and zignorm_r().
