如何画出均匀，指数和weibull分布的概率密度函数图
Can you (re)produce a figure that compares the capacity of exponential distribution (mean 100), uniform distribution (from 0 to 200), and Weibull distribution (\beta=0.5, and \mu=50), as a function of collision probability constraint, assuming the percentage of idle time is 50% in all cases? If so, please send me the figure as well as the matlab code.
问题如上 谢谢各位
