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.
