Abstract :In this study, we deal with an $m$ banded circulant matrix, generally called circulant $m$-diagonal matrix. This special family of circulant matrices arise in many applications such as prediction, time series analysis, spline approximation, difference solution of partial differential equations, and so on. We firstly obtain the statements of eigenvalues and eigenvectors of circulant $m$-diagonal matrix based on the Chebyshev polynomials of the first and second kind. Then we present an efficient formula for the integer powers of this matrix family depending on the polynomials mentioned above. Finally, some illustrative examples are given by using maple software, one of computer algebra systems insert ignore into journalissuearticles values(CAS);.
Keywords : Chebyshev polynomial, Circulant matrix, Eigenvalue, Eigenvector
