RAND('state',0) resets the generator to its initial state.
RAND('state',J), for integer J, resets the generator to its J-th state.
3 {& F# o( M) g) RRAND('state',J) and RAND('state',S) cause the MATLAB 5 generator to be used.
help 里面解释
rand('state',s)Resets the state to s.
rand('state',0)Resets the generator to its initial state.
& q5 l! }: B  N9 L9 z/ }rand('state',j)For integer j, resets the generator to its j-th state.

rand('state',s)表示随机产生数的状态state，一般情况下不用指定状态。但是有的书籍作者为了让读者能够看到和他书本的同样结果，采用了设置state，rand('state',0)作用在于如果指定状态，产生随机结果就相同了。
