چکیده
|
We prove that any k-circulant matrix and any even order skew k-circulant matrix are diagonalizable for any k. then,we propose two algorithms for computing the square roots of the k-circulant matrix and the skew k-circulant matrix,respectively. in particular,we show that the square roots of the k-circulant matrix are still k-circulant matrices. both the theoretical analysis and the numerical experiments show that our algorithms are faster than the standard schur method. © 2013 ying zhang et al.
