| Abstract: | In this paper, the authors take advantage of the reducibility of the generalized centro-symmetric matrix and the generalized centrohermitian matrix to propose two fast algorithms for computing the products of such matrices. It is showed that our algorithm is half of the amount of computation to that of the conventional algorithm. |
