摘要
研究了半正定矩阵的广义Schur补的任意扰动,给出了广义Schur补在谱范数下的绝对扰动界,改进并推广了以往的结果.
An arbitrary perturbation of generalized Schur complement for positive semidefinite matrix is studied. Then a perturbation bound of the matrix under the spectrum norm is presented, which improves and generalizes the corresponding results in the references.
