Usage: z_normal(s,mu,sigma); - v# Q4 b6 `% `: N7 j
The expression s (integer) defines the random number stream, while mu and sigma define mean and deviation of the normal distribution.7 _6 `' q7 w. z
里面的s表示什么意思啊?4 T3 N ^* [1 Z
我主要是The expression s (integer) defines the random number stream中的stream不太理解。0 ^% ]3 r- H9 n S
谢谢各位帮忙!3 ^& r' Y9 Y+ i' _8 m
0 [5 E1 b/ i6 ~. K# [5 P2 }
