Usage: z_normal(s,mu,sigma); ' K- ^ z+ s9 {9 g9 A/ o8 q- ~% n3 i) g. l
The expression s (integer) defines the random number stream, while mu and sigma define mean and deviation of the normal distribution.+ t5 B! @, ~+ a( A* T
里面的s表示什么意思啊?
! W' K2 n5 |& u" ^' z/ d% s我主要是The expression s (integer) defines the random number stream中的stream不太理解。* I- w" m& ^8 V! @
