This article is about the relation between structured matrices and integer sequences. The authors [Appl. Math. Comput. 437, Article ID 127521, 13 p. (2023; Zbl 1510.11059)] already considered r" role="presentation">-circulant matrices containing Narayana numbers to examine this relationship. Here they obtain estimates for spectral norms and eigenvalues of r" role="presentation">-circulant matrices with entries from a Fibonacci-Narayana sequence, thus providing, for example, conditions for invertibility. There are many applications in physics, engineering, economics, signal theory and image processing for this kind of results.
