摘要
给出了3、4阶方阵A的特征矩阵λE－A的等价标准形的数值解法，借助于复合矩阵刻划了λ－a在Dk（A（λ））中的指数，从而给出了一般情况下A（λ）的等价标准形的数值解法框架。
In this article, we depend on the compound matrix to describle the index df λ-a in Dk (A(λ) ), and therefore on the relation of the determinant factor and the unchanged factor to make a plan for the solution to the numerical value of λ- matrix equivalent standard form.ln this article, we first give out the solution to the numerical value of λE - A equivalent standard form, i. e. A characteristic matrix in 3. 4 grade matrix; and then with the help of compound matrix, describle the index of λ - a in Dk(A(λ) ) and therefore give out the outline of the solution to the numerical value of A (λ) equivalent standard form in the most time.
