摘要
研究了r-循环矩阵的简化形式,提出了一种计算r-循环矩阵平方根的新算法,该方法无需计算r-循环矩阵的特征值,计算时只需要矩阵乘法的迭代.
A simplified form of r-circulant matrices is investigated, and a new algorithm to compute the square roots of r-circulant matrices is obtained using the properties of r-circulant matrices. In stead of calculating the eigenvalues of the r-circulant matrices, the proposed method only needs inter-matrix multiplication in its iterative sequence.
