关于 r-循环矩阵与 r-循环对称矩阵的逆

THE INVERSE MATRICES OF r CYCLE MATRICESAND r SYMMETRIC CYCLE MATRICES

利用关联多项式及其根给出了ｒ－循环矩阵的逆的２种表达式及算法，并对ｒ＝１，ｎ为偶数的情形提出了一种降阶算法．

Using related polynomial and its roots, we give two expressions and algorithms for the inverse matrices of r cycle matrics and put forward a matrix deflation algorithm when r =1, and n is an even. 〖WT5FZ〗
