Usage: z_normal(s,mu,sigma); ' X9 Q$ Z, g5 p* Q% E) p5 ~5 m% g9 h+ M
The expression s (integer) defines the random number stream, while mu and sigma define mean and deviation of the normal distribution.1 V0 t9 U$ i Z
里面的s表示什么意思啊?3 L0 v7 f( R8 m, u- ~& o, y+ f
我主要是The expression s (integer) defines the random number stream中的stream不太理解。0 @8 n' f- |8 d+ u8 u, O1 _% b$ E
谢谢各位帮忙!
