面向对象就是把构成问题事务分解成各个对象,建立对象的目的不是为了完成一个步骤,而是为了描叙某个事物在整个解决问题的步骤中的行为,比如第三次作业中解一元二次方程,创建一个QuadraticEquation类的对象equation,然后这个equation对象在主函数中调用自己getRoot1,getDiscriminant等方法,在QuadraticEquation类中定义了自己的...

A为n阶矩阵，若数λ和n维非0列向量x满足Ax=λx，那么数λ称为A的特征值，x称为A的对应于特征值λ的特征向量。式Ax=λx也可写成( A-λE)x=0，并且|λE-A|叫做A 的特征多项式。当特征多项式等于0的时候，称为A的特征方程，特征方程是一个齐次线性方程组，求解特征值的过程其实就是求解特征方程的解。
