使用SHELL实现泊松分布，指数分布。对于模拟网路流量和拥塞阻塞分析特别有用处。实现用户数据泊松到达，数据包大小指数分布。-SHELL achieved using the Poisson distribution, exponential distribution. For the simulation analysis of network traffic and congestion congestion particularly useful. Poisson arrival achie

vb 按泊松分布计算的概率 机械可靠性设计-vb calculated by the Poisson distribution the probability of mechanical reliability

产生服从正态,瑞利,泊松分布的随机数,分别为N(0,1),N(0,3 6),Rayleigh(0,1),R(0,3 6),P(()
