矩阵的降阶定理及其应用

Matrix Reduction Theorems and Their Application

给出了矩阵求逆的几个降阶定理,利用这些定理可将求高阶矩阵的逆转化为求低阶矩阵的逆,并由定理导出了两个推论,这些定理及其推论在求逆矩阵的过程中具有重要的意义.

Several reduction theorems for matrix inversion are given, so matrix inversion of high demand can be converted into that of low demand by these theorems. Two inferences are derived by the theorems, both theorems and their inferences have important significance in matrix inversion.
