正定矩阵(Positive-definite Matrix) 原文链接 正定矩阵是自共轭矩阵的一种。正定矩阵类似复数中的正实数。定义:对于对称矩阵M,当且仅当存在任意向量x,都有 若上式大于等于零,则称M为半正定矩阵。正定矩阵记为M>0。 也被称为正定二次型 正定矩阵的判定 1、所有特征值为正数(根据谱定理,若条件成立,必然可以找到...

A positive (semi-)definite matrix is a square matrix with the following property: (1.63)x′Ax=x′12(A+A′)x≥0,∀x. If the inequality is strictly greater, it is positive definite, otherwise positive semi-definite. From the definition, we can see that A is positive (semi-)definite...
