求分块鳞状因子循环矩阵逆矩阵的一种快速算法
A fast algorithm for the inversion of matrices with scaled factor circulant blocks
摘要
Abstract
A fast algorithm to compute the inversion of matrices with scaled factor circulant blocks is presented.The method is based on the discrete Fourier transform and the application of a recursive algorithm for the inversion of the block diagonal matrices.It is showed that the algorithm is far more efficient than the LU decoposition method.关键词
