关于循环矩阵逆平方根矩阵的计算(On the computation of the inverse square roots of circulant matrices)

Abstract

First the properties of circulant matrices are investigated, and two algorithms to compute the inverse square roots (by matrix reduced-order method) are presented. It is showed that these two algorithms are of significant savings in computational costs as compared with the existed methods.

Keywords

• circulant matrix
• inverse square root
• reduced form
• schur decomposition
