Méthode générale de résolution de la similarité conjuguée en polarimétrie radar

, 2022
National audienceThis work aims to offer a clear overview of equivalence relations applicable in radar polarimetry. The focus is on the conjugatesimilarity transformation, frequently mentioned and seldom used with the coherent decomposition methods.

Regularizing algorithm for mixed matrix pencils

P. Van Dooren (1979) constructed an algorithm for computing all singular summands of Kronecker’s canonical form of a matrix pencil. His algorithm uses only unitary transformations, which improves its numerical stability.

A canonical form for matrices under consimilarity [PDF]

Linear Algebra and Its Applications, 1988
Complex \(n\times n\) matrices A, B are said to be consimilar if \(B=S^{- 1}A\bar S\) for some non-singular complex matrix S. This concept arises naturally from comparing the expressions for a semilinear transformation on an n-dimensional complex vector space in two different coordinate systems.

Similarity and consimilarity of hyper‐dual generalized quaternions [PDF]

Mathematical Methods in the Applied Sciences
The aim of this paper is to investigate similarity and consimilarity of hyper‐dual generalized quaternions and their matrices. For this purpose, we give different conjugates according to the generalized quaternionic units . We present ‐consimilarity of hyper‐dual generalized quaternions and their matrices except hyper‐dual ‐quaternions.

A Hermitian canonical form for complex matrices under consimilarity [PDF]

Linear Algebra and Its Applications, 1990
An algorithm is described that yields a Hermitian canonical form for complex matrices under consimilarity. It consists of three blocks corresponding to the nonnegative, negative and nonreal eigenvalues of \(A\bar A\). A similar algorithm produces a real canonical form (for complex matrices under consimilarity).
