本代码为数学物理方程研究课题的一部分，编码实现了数值解析法，分离变量法，有限差分法，对几类方法进行了仿真(This code is part of the research in mathematical physics equations, coding to achieve a numerical analysis method, separation of variables method, finite difference method, several types of methods for simulation)

用Romberg法求积分计算准确，while循环次数一般不超过10，运算较为方便、快捷；计算之前，需要给出所求函数的表达式，积分上限和下限以及误差范围。运用MATTLAB程序求解积分省时、省力。(用Romberg法求积分计算准确，while循环次数一般不超过10，运算较为方便、快捷；计算之前，需要给出所求函数的表达式，积分上限和下限以及误差范围。运用MATTLAB程序求解积分省时、省力。用Romberg法求积分计算准确，while循环次数一般不超过10，运算较为方便、快捷；计算之前，需要给出所求函数的表达式，积分上限和下限以及误差范围。运用MATTLAB程序求解积分省时、省力。自动检测中英文中译英英译中百度翻译. 翻译结果（中 > 英）复制结果 Using Romberg method for integral calculation accuracy, while cycle number less than 10, operation more convenient, fast calculation before, given the need for function expression, integral upper and lower as well as the error range.
