The algorithm for radication of r-circulant matrix of type 2~k

HUANG De-chao(College of Information and Engineering, Hangzhou Teachers College, Hangzhou 310012, China)  
In this paper, we present an algorithm for radication of r-circulant matrix of type 2~k computation radical similar matrices by using reduced-order method.We prove that the number of all radical similar matrices is 2~n, the algorithm only demands O(nlog_2n) for calculating one radical similar matrix and the algorithm demands O(n2~nlog_2n) arithematic operations for calculating all radical similar matrices.
