正定和半正定矩阵可以用多种方式来表征,这也许可以解释该概念在数学各个部分的重要性。矩阵M 是正定的(positive-definite )当且仅当它满足以下任何等效条件。 M 与具有正实数项的对角矩阵全等( congruent with a diagonal matrix with positive real entries.)。 M 是对称或 Hermitian 的,其所有特征值都是实数和正...

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...
