Usage: z_normal(s,mu,sigma); - q; ~( `* b' r* O
The expression s (integer) defines the random number stream, while mu and sigma define mean and deviation of the normal distribution.
% S$ O6 P. M/ I' w) t+ R里面的s表示什么意思啊?
6 O% ^6 j3 O i6 R0 L& J* P我主要是The expression s (integer) defines the random number stream中的stream不太理解。3 o2 ?5 t. j$ r. A+ _
谢谢各位帮忙!4 A/ }/ K& }3 M0 ]
