电力系统潮流计算 采取牛顿-拉弗逊法和PQ分解法 用matlab计算矩阵的功能，通过迭代方式求解。-power flow calculation taken Newton-Laffer Robertson and PQ decomposition matrix calculation using Matlab gong able, through iterative method to solve.

用牛顿法解方程组，迭代法解方程组和求矩阵最大特征值-Newton Method with equations, iterative methods for solution of matrix equations and the largest eigenvalue

牛顿迭代法（Newton s method）又称为牛顿-拉夫逊（拉弗森）方法（Newton-Raphson method），它是牛顿在17世纪提出的一种在实数域和复数域上近似求解方程的方法。-Newton iterative method (Newton s method) is also known as Newton- Ralph monson (laffer sen) method (Newton Raphson method), it was proposed by Newton in
