正定矩陣的判斷 Positive Definite Matrix 正定矩陣的判斷 Positive Definite Matrix 如何判斷一個矩陣是否為正定矩陣？ 首先，請先特別注意到我們所討論的正定矩陣必須有對稱的性質。 （有些書上定義上不要求對稱） 要判斷一個矩陣是否正定，當然我們可以從其定義來做，不過可以發現，粉 ...

positive definite | planetmath.org One can show that a Hermitian matrix is positive definite if and only if all its eigenvalues are positive [1]. Thus the determinant of a positive definite matrix is positive, and a positive definite matrix is always invertible.
Positive Definite Matrix -- from Wolfram MathWorld An n×n complex matrix A is called positive definite if R[x^*Ax]>0 (1) for all nonzero complex vectors x in C^n, where x^* denotes the conjugate transpose of the vector x. In the case of a real matrix A, equation (1) reduces to x^(T)Ax>0, (2) where x^(T) d
