基于循环矩阵理论及其相关研究成果,定义了首尾差r-循环矩阵(简记为FLDCMr),研究了它的判别法和对角化问题,给出了求其逆与广义逆的快速算法,并探讨了对其开平方与开m次方的快速算法.
A new type of circulant matrices,called the first and the last difference r-circulant matrix(FLDCMr),is presented based on the theory of cyclic matrix and its related research results.Its discriminant and diagonalization problem is studied;the fast algorithm of inverse and generalized inverse is given;and the fast algorithm for its square and open m-th power is discussed.
