Then, a preconditioner with a decomposed matrix form is built easily by LDU ( lower-diagonal-upper) decomposition and a simplified blocked Gauss elimination algorithm.

Finally, this method is applied to proving the LDU factorization of matrices with all main subdeterminants being non-zero and some relative results.

最后应用这一方法证明了各阶主子式不为零矩阵的LDU分解及一些相关的结果。
