用蒙特卡罗算法计算定积分，其中用了随机数函数。-Monte Carlo algorithm to calculate the definite integral, which used the random number function.

蒙特卡罗算法的实现，蒙特卡罗算法是进行根据概率进行预测的方法，在众多领域广泛应用-Monte Carlo algorithm, Monte Carlo algorithm is a prediction based on probability approach, widely used in many fields

蒙特卡罗法主算法，相关函数需要调用的可根据实际项目需要编写。-Monte Carlo main algorithm, the correlation function may need to call the project based on the actual need to write.
