摘要
利用矩阵的次转置共轭和翻转矩阵等技巧,给出关于斜正定矩阵的一些性质,给出矩阵的斜对称部分与其逆之差是斜半正定的结论.
Some properties on persymmetric positive definite matrix and the result that difference between persymmetric part of a matrix and its inversion is semipersymmetric are investigated by means of pertransposition conjugation of matrix and flip matrix.
