A new efficient computational algorithm to find the determinant of a general pentadiagonal matrix is presented. The algorithm is suited for implementation using computer algebra systems such as MAPLE, MATHEMATICA, MATLAB and MACSYMA.doi:10.1016/j.amc.2007.09.005Ahmed Driss Aiat Hadj...
We also study the convergence of L-BFGS method if we use the BFGS and inverse BFGS update of the diagonal matrix on uniformly convex problems.M. L. SahariKhaldi RActa Mathematica Universitatis ComenianaeActa Mathematica Universitatis Comenianae...
Theorem 17 generalizes a result of Brouwer and Van Eijl [2] on the Smith form of the adjacency matrix of the line graph of a complete graph. The current work is motivated in part by a certain zero-sum Ramsey-type problem introduced by N. Alon and Y. Caro [1]. Let H be a t-...

Let G be a simple graph on the vertex set \\\({\\\{1,\\\ldots,n\\\}}\\\) with m edges. An algebraic object attached to G is the ideal P G generated by diagonal 2-minors of an \\\({n imes n}\\\) matrix of variables. We prove that if G is bipartite, then every ini...
matrixIn the current article, the authors present a new recursive symbolic computational algorithm, that will never break down, for inverting general periodic pentadiagonal and anti-pentadiagonal matrices. It is a natural generalization of the work presented in [M.E.A. El-Mikkawy, E.D. Rahmo,...
In this paper, by using a special matrix factorization, a symbolic computational algorithm is developed to solve the cyclic penta-diagonal linear system. The algorithm is suitable for implementation using Computer Algebra Systems (CASs) such as MATLAB, MATHEMATICA and MAPLE. In addition, an ...
