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...

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 ...
A symmetric positive definite matrix has n eigenvalues which are all real positive numbers. (3) The determinant of a symmetric positive definite matrix is positive. (4) A minor of A is a submatrix obtained by deleting some rows and some columns. A principal minor is obtained when identical ...
Or, by stating an equation for the coefficients using indices i and j, Example: Find the Hessian matrix of the functionf(x,y,z)=sin(xyz) We now compute the second partial derivatives off: Therefore the Hessian matrix offis: 6. Positive Definite ...

In this paper, we further extend the ST decomposition to the generalized saddle point problems (1.1) when C is a general symmetric and positive semi-definite matrix. The obtained block triangular matrices T are also called the ST preconditioners. A general approach to get the ST preconditioners ...
