) 摘要: 积分的近似计算在许多实际工程的应用十分广泛,可积系统的一大类问题事实上就是不规则区域上高维积分问题
这类问题绝大多数按数学的研究处理模式出发,都是难以解决的,而蒙特卡罗方法对计算高维空间中维数不很高且积分区域是规则的积分、以及复杂区间甚至不连通的区域上的积分都却是很方便的
本文主要介绍了蒙特卡罗法计算数值积分的两种方法:随机投点法和平均值法,并且具体给出了这两种方法的计算原理以及方法步骤,然后结合Matlab数学软件,用具体实例给出了定积分和多重积分的计算求解过程
关键词: 蒙特卡罗方法
) Abstract: The approximate calculation of integrals has a wide range of applications in many practical engineering, in fact a big problem of integrable system is the issue of high-dimensional points in the irregular region
These issues are mostly difficult to solve according to the general study of mathematical models, but the Monte-carlo method is very convenient for calculating Multiple Integral of low dimension in regular domain of integration or complex range or even non-connected region
This paper mainly introduces the two methods of Monte-Carlo:Random Vote Method and Average Method, and concretely gives their principles and method steps
Besides, it combines Mathematical software Matlab to give the solving process of Definite integral and multiple points
