Companion Supplement: Extended Numerical Evaluation and Exact Examples for "State-Feedback Assignment for Quaternionic MIMO Systems: Brunovský Forms, Robust qKNV, and Target Intertwiners"

Abstract

This independently archived companion supplement accompanies the manuscript “State-Feedback Assignment for Quaternionic MIMO Systems: Brunovský Forms, Robust qKNV, and Target Intertwiners,” submitted to the IEEE Transactions on Automatic Control on 22 August 2026. It contains four exact worked examples, detailed conditioning and backward-error analysis, the complete deterministic numerical protocol, and extended tables and figures for diagonal, repeated-class, coupled-target, Sylvester-separation, and complex-adjoint experiments. The associated manuscript is mathematically self-contained. This Zenodo record is independent of the IEEE Xplore record and provides a permanent, citable location for the additional material. Version 1.0 corresponds to the initial TAC submission. No software, raw data, or reproducibility archive is included in this record.
