摘　　要：就具有对称不定系数矩阵的线性方程组，提出广义ＬＤＬＴ分解法．该方法具有ＬＤＬＴ分解法的优点，故运算量比广义Ｃｈｏｌｅｓｋｙ分解法少．A generalized LDL T factorization method for solving linear equations with symmetric indefinite coefficient matrix is proposed.The method has the advantage of the LDL T factorization method, so its operation amount is less than that of the generalized Cholesky factorization method.

关 键 词：线性方程组 对称不定矩阵 广义 LDL^T分解法
