【摘要】 借助快速付立叶变换(FFT),本文给出一种求n阶鳞状因子循环矩阵的逆阵、自反g-逆、群逆、Moore-Penrose逆的快速算法,该算法的计算复杂性为O(nlog2n),最后给出的两个数值算例表明了该算法的有效性.
【Abstract】 A fast algorithm for calculating the inverst and self-reflective g-inverse and group inverse and Moore-Penrose inverse of the scaled factor circulant matrices of order n is presented by the fast Fourier transform (FFT). its complexity is O(nlog2n),Fanally, numerical examples show the effectiveness of this algorithm.
