摘要
本文直接由二次系统的系数给出了焦点量的算法,用muMATH软件在IBM—PC机上进行符号运算并化简,导出了计算焦点量的最简公式。
In this paper, an algorithm for determining the focal values of the quadratic sys- tem is given directly by the coefficients of the system. Through the signs operation in IBM-PC with muMATH, the simplest formular for the focal values is obtained.
