| Abstract: | This paper describes the design and program realization of an algorithm sampling from arbitrary distribution,this algorithm uses the alias method.The two functions we have now can sample from any discrete distribution and one -dimensional continuous distribution.The num-erical examples show that the program and the method are very effective. |
