Influence Of Jacobi Matrix Conditionality On Stability Of Mutlibody Simulations

The danger of multibody simulations instability comes with increasing model complexity. Jacobi matrix conditionality has direct influence on computation quality. The aim of this report is to refer to possibilities of simulation kont...

On the eigenvalue problem for a particular class of finite Jacobi matrices

of the function F is given for the determinant of a Jacobi matrix. Further we focus on the particular class of Jacobi matrices of odd dimension whose parallels to the diagonal. A special basis is constructed in which the <...

Factorization of the characteristic function of a Jacobi matrix

In a recent paper a class of in nite Jacobi matrices with discrete character of spectra has been introduced. With each Jacobi matrix from this class an analytic function is associated, called the characteristic function, wh...

The Algebraic Riccati Equation for Quaternions.

We will present the general solution of the algebraic Riccati equation for the quaternionic case, where also one additional variation is treated. For computational purpose a very simple form of the exact Jacobi matrix for Riccati po...
