A Note on the Square Roots of a Class of Circulant Matrices

We prove that any k-circulant matrix and any even order skew k-circulant matrix are diagonalizable for any k∈ℂ. 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...
