A negative definite n×n matrix A has all its eigenvalues negative and satisfies the relation (10.3)vT·A·v<0 for every n×1 vector v. If A is negative definite, then A−1 exists and is also negative definite. For simplicity of notation, the negative definiteness is often denoted as...

If C is any matrix, either square or rectangular, then A = CTC is symmetric non-negative definite. A is clearly symmetric. To show that A is non-negative definite, consider any non-null vector x of the appropriate length. Then xTAx = xTCTCx = (Cx)T(Cx)≥ 0. Besides, if the colu...

在多元情况下，二次项部分的分析通过矩阵表示进一步简化。二阶偏导矩阵称为海森矩阵（Hessian Matrix），其正负性质决定函数在特定点的极值性质。若海森矩阵的特征值全为正，表明该点为局部最小值；若全为负，则为局部最大值；否则，无法断定。正定矩阵与上述概念紧密相连，它们在矩阵分析、线性代数和优化...
