对角阵非齐次特征值问题的讨论

一些工程问题，例如：工程结构计算、投入产出模型，常常遇到对角阵非齐次特征值的问题，给出了不同条件下，非齐次问题的特征值、特征向量的存在性，并给出相应的计算方法，最后通过实例验证所述理论及计算方法的正确性和有效性。

Discussion on non-homogeneous eigenvalue of diagonal matrices

In some engineering problems,such as calculation on engineering structure and input-output model,put in-produce out pattern,the question of Non-homogeneous Eigenvalue of Diagonal Matrices has been met usually. The exitence of eigenvalue and eigenvector under different conditions is introduced,and the relevant calculated methods are obtained. Finally, the rightness and effectiveness of the thory and calculated method are tested by some examples.
