Usage: z_normal(s,mu,sigma); % \6 {- {6 v% z! H r ~/ g
The expression s (integer) defines the random number stream, while mu and sigma define mean and deviation of the normal distribution. R ^* {) w: n& r0 u
里面的s表示什么意思啊?$ W! \; I1 `. C- } D( h
我主要是The expression s (integer) defines the random number stream中的stream不太理解。" J2 x" z6 b1 e: U/ s4 [
谢谢各位帮忙! : m! _9 q7 m! k- T# @) \6 [9 K+ Y2 E
