1) symmetric positive definite matrix 对称正定矩阵 1. In 1970, the notion of unnecessary symmetric positive definite matrix was firstgiven by C. Johnson在[1]中提出了未必对称的正定矩阵的概念(对任何0≠X∈Rn×1,都有X T AX>0),并得到了这种正定矩阵的某些不等式[2];1984年,佟文廷教授在[5]中...
A summary of properties follows. (1) If A and B are symmetric positive definite, A + B is also symmetric positive definite. This is a useful property because frequently a large matrix is obtained as the sum of smaller ones, which are known to be positive definite. Besides, it is ...
Every realnon-singular matrix(TODO) can be uniquely factored as the product ofan orthogonalmatrixanda symmetric positive definite matrix, which is calleda polar decomposition. Singular matrices can also be factored, but not uniquely. Cholesky decomposition(TODO) states that every real positive-definite ...

This dissertation is motivated by addressing the statistical analysis of symmetric positive definite (SPD) matrix valued data, which arise in many applications. Due to the nonlinear structure of such data, it is challenging to apply well-established statistical methods to them. Our goal is to ...
First, an unsymmetric tridiagonal matrix T is transformed into a symmetric tridiagonal matrix T *. 首先将非对称三对角矩阵T化为对称三对角矩阵T ,对于对称三对角矩阵T 和位移σ ,给出由T 求其简化矩阵 ^T的算法。 3. The convergence of QL algorithm with shifts for symmetric tridiagonal matrix is ...
if the matrix of second derivatives is positive definite, you're at a local minimum. if the matrix of second derivatives is negative definite, you're at a local maximum. otherwise, you are at neither, a saddle point. you can understand this with the geometric reasoning above in an ...
网络对称正肯定矩阵;对称正定矩阵 网络释义
A symmetric positive definite matrix is a square matrix where all the elements are real numbers and the matrix is equal to its own transpose. Additionally, all the eigenvalues of a symmetric positive definite matrix are positive. This type of matrix has many useful properties, such as being inv...
