Toeplitz 方程组的拟对称化快速算法

摘要

利用由 n阶Toeplitz矩阵构造的2n阶拟对称矩阵，给出了求解 Toeplitz方程组的拟对称化快速算法。该算法与已有算法相比，或者减少了计算量，或者提高了计算精度。%In this paper ,we got an pseudo symmetric fast algorithms for solving Toeplitz systems by constructing a spe-cial block matrix .In contrast with previous methods ,new algorithms reduce operations or improve precision .
