In this paper a new algorithm for reducing an arbitrary real square matrix to tri-diagonal form using real similarity transformations is described. The method is essentially a generalization of a ...

Recent studies have explored the introduction of integrable defects in Yang‐Baxter models by utilising modified monodromy matrices and the concept of frozen Bäcklund transformations [1].
