利用Matlab近似计算圆周率的若干方法

Some Methods of Approximatively Calculating Using Matlab Experiments

本文分别采取幂级数展开式的方法、随机数的方法、数值积分的方法和公式法结合Matlab程序实现对圆周率的近似计算，分析实验结果，比较每种方法的近似程度的高低，实现了Matlab实验和数学理论的很好结合。

In this paper, we used expanding power series, random number, numerical integration and formula methods com- bining matlab experiments to achieve the approximate value of. Then, we analyzed the experiments results, and compared the degree approximation of every method. It achieved the satisfying results of combination withMatlab experiment and mathematics theory.
