Gaussian Fibonacci Circulant Type Matrices [PDF]
Abstract and Applied Analysis, 2014 Circulant matrices have become important tools in solving integrable system, Hamiltonian structure, and integral equations. In this paper, we prove that Gaussian Fibonacci circulant type matrices are invertible matrices for n>2 and give the explicit ...

On the Eigenvectors of Generalized Circulant Matrices
Linear and Multilinear Algebra, 2023 In \cite{Mourad}, Kaddoura and Mourad, in order to widen the scope of the class of circulant matrices, (see \cite{Davis}), constructed circulant-like matrices that were called generalized weighted circulant matrices.

Hadamard matrices constructed by circulant and negacyclic matrices
Australas. J Comb., 2006 In this paper we establish a correspondence between circulant and negacyclic matrices of order n for n odd, give the definition of suitable matrices, and show several new methods for constructing compsite suitable negacyclic (circulant) matrices from ...

On the determinants of some kinds of circulant-type matrices with generalized number sequences
Special Matrices, 2015 Recently, determinant computation of circulant type matrices with well-known number sequences has been studied, extensively. This study provides the determinants of the RFMLR, RLMFL, RFPrLrR and RLPrFrL circulant matrices with generalized number ...

Cartesian MaxGIRF: Model-based EPI reconstruction incorporating gradient nonlinearity and concomitant field effects. [PDF]
Magn Reson MedAbstract Purpose Lower field strength scanners with large bore size or complex geometries, and scanners with stronger gradient systems experience increased gradient nonlinearity and concomitant fields, each of which causes distortions in EPI. Current correction approaches based on image‐domain interpolation introduce undesirable spatial blurring.

International Journal of Robust and Nonlinear Control, EarlyView., 2023 Abstract We propose a hierarchical energy management scheme for aggregating Distributed Energy Resources (DERs) for grid flexibility services. To prevent a direct participation of numerous prosumers in the wholesale electricity market, aggregators, as self‐interest agents in our scheme, incentivize prosumers to provide flexibility. We firstly model the

Double circulant matrices [PDF]
Linear and Multilinear Algebra, 2017 Double circulant matrices are introduced and studied. A formula to compute the rank r of a double circulant matrix is exhibited; and it is shown that any consecutive r rows of the double circulant matrix are linearly independent. As a generalization, multiple circulant matrices are also introduced.
