On the g-Jacobi Matrix Functions

2013
In this paper, we introduce a matrix version of the generalized Jacobi (g-Jacobi) function, which is a solution of fractional Jacobi differential equation, and study its fundamental properties. We also present the fractional hypergeometric matrix function as a solution of the matrix generalization of the fractional Gauss differential equation.

Jacobi- und Hesse-Matrix

1995
Mit dem Konzept der partiellen Ableitung verknupft sind Jacobi- und Hesse-Matrix, sowie Divergenz, Rotation und Laplace-Operator. Hierfur stellt Maple entsprechende Befehle bereit, auf die wir jetzt eingehen.

Inverse Spectrum Problems for Block Jacobi Matrix

1993
A spectrum function for the block Jacobi matrix is defined which allows to determine conditions for existence and uniqueness for the corresponding inverse spectrum problem. Two numerical algorithms for solving the inverse spectrum problem are proposed and their behaviour is illustrated on several examples of order up to 15.

The Jacobi Matrix for Functions in Noncommutative Algebras

Advances in Applied Clifford Algebras, 2014
The authors develop a general tool for constructing the exact Jacobi matrix for functions defined in noncommutative algebraic systems without using any partial derivative. The construction is applied to solving nonlinear problems of the form \(f(x) = 0\) with the aid of Newton's method in algebras defined in \({\mathbb{R}^N}\).

A matrix model for the β-Jacobi ensemble

Journal of Mathematical Physics, 2003
This note presents a random matrix model for general (β>0) β-Jacobi ensembles. This generalizes the well-known MANOVA models for β=1,2,4 and eliminates the quantization of β (and other parameters) present in the previously known models. This model is a partial answer to an open problem presented by Dumitriu and Edelman, where they also presented

Jacobi-Matrix: Grundlagen und Algorithmen

1994
Die Steuerung von Roboterarmen basiert auf zwei Transformationen, die kinematisch vom Gelenkraum in den kartesischen Raum und umgekehrt vermitteln. Dies sind die Hintransformation \(\overrightarrow {\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}\to {\Lambda } } \) bzw.

EXTENDED JACOBI MATRIX POLYNOMIALS

2013
In this paper, extended Jacobi matrix polynomials (EJMPs) are introduced. The matrix differential equation satisfied by them is given. A Rodrigues formula, orthogonality, linear generating matrix functions and recurrence relations are presented for these matrix polynomials. Furthermore, general families of multilinear and multilateral generating matrix
