Usage: z_normal(s,mu,sigma); 6 I7 `* z J% {8 x
The expression s (integer) defines the random number stream, while mu and sigma define mean and deviation of the normal distribution. 6 `) `9 u/ a3 B& s+ Q( ]" x里面的s表示什么意思啊? 9 q/ P# @! g; w" J/ D我主要是The expression s (integer) defines the random number stream中的stream不太理解。+ X$ f% A- H/ _4 A$ V
谢谢各位帮忙! 5 J9 A0 u) z0 I) {" \! _ P( W% Z D
