Stability of the Diagonal Pivoting Method With Partial Pivoting [PDF]

open access: yesSIAM Journal on Matrix Analysis and Applications, 1997
LAPACK and LINPACK both solve symmetric indefinite linear systems using the diagonal pivoting method with the partial pivoting strategy of Bunch and Kaufman [Math. Comp., 31 (1977), pp. 163--179]. No proof of the stability of this method has appeared in the literature.

Stability of Matrix Polytopes with a Dominant Vertex and Implications for System Dynamics

open access: yesAbstract and Applied Analysis, 2013
The paper considers the class of matrix polytopes with a dominant vertex and the class of uncertain dynamical systems defined in discrete time and continuous time, respectively, by such polytopes. We analyze the standard concept of stability in the sense

Stable approach based diagonal recurrent quantum neural networks for identification of nonlinear systems [PDF]

open access: yesScientific Reports
Identification of nonlinear dynamics from input-output data is crucial in many fields where conventional linear models fail to capture nonlinear dynamics of complex systems.

Effects of Head-Neck Position and Ground Surface on Gait Kinematics in Ridden Brazilian Criollo Horses [PDF]

open access: yesAnimals
The Criollo horse is prized for its endurance, yet its specific biomechanical signatures remain under-researched. This study investigated diagonal dissociation and support patterns in eleven clinically sound Criollo horses to understand the influence of ...

The Effect of Grid-Connected Converter Control Topology on the Diagonal Dominance of Converter Output Impedance

open access: yesIEEE Open Access Journal of Power and Energy, 2023
This work investigates the effect of grid-connected converter topology on equivalent converter output impedance with a specific focus on the diagonal dominance of the impedance matrix across a frequency range.

Diagonal Interactions between Glutamate and Arginine Analogs with Varying Side-Chain Lengths in a β-Hairpin

open access: yesMolecules, 2023
Cross-strand interactions are important for the stability of β-sheet structures. Accordingly, cross-strand diagonal interactions between glutamate and arginine analogs with varying side-chain lengths were studied in a series of β-hairpin peptides.

Balance Control of a Quadruped Robot Based on Foot Fall Adjustment

open access: yesApplied Sciences, 2022
To balance the diagonal gait of a quadruped robot, a dynamic balance control method is presented to improve the stability of the quadruped robot by adjusting its foot position.

Diagonal Riccati stability and applications [PDF]

open access: yesLinear Algebra and its Applications, 2016
We consider the question of diagonal Riccati stability for a pair of real matrices A, B. A necessary and sufficient condition for diagonal Riccati stability is derived and applications of this to two distinct cases are presented. We also describe some motivations for this question arising in the theory of generalised Lotka-Volterra systems.

Diagonal Riccati stability and the Hadamard product [PDF]

open access: yesLinear Algebra and its Applications, 2017
We present an extension of a recent characterisation of diagonal Riccati stability and, using this, extend a result of Kraaijevanger on diagonal Lyapunov stability to Riccati stability of time-delay systems. We also describe a class of transformations that preserve the property of being diagonally Riccati stable and apply these two results to provide ...
