摘要
在高次方程正项分解的基础上给出了一个用Newton法求解实系数高次方程正数根的计算方法 .该方法具有迭代初值选取条件宽松的优点 ,容易改进为求解实系数高次方程全部实数根的大范围收敛性迭代解法 .
Based on resolution on the positive terms for equations of higher order, an iterative technique to find a positive real root of equations of higher order with real coefficients is given by New ton’s method. The technique possesses an advantage of free condition for choos ing initial iterative values. It can be improved to the iteration method with global convergence for finding all real roots.
