On the Scalar Measure of Non-Normality of Matrices – Dimension vs. Structure
Abstract The aim of this paper is to analyze the relative importance of the dimension and the structure of the square…
On some one-step implicit methods as dynamical systems
Abstract The one-step implicit methods, the backward Euler being the most known, require the solution of a nonlinear equation at…

Generalized random walk algorithm for the numerical modeling of complex diffusion processes
Abstract A generalized form of the random walk algorithm to simulate diffusion processes is introduced. Unlike the usual approach, at…
On approximating the inverse of a matrix
Abstract In this note we deal with two problems: the first regards the efficiency in approximating the inverse of a…
On the convergence order of some Aitken-Steffensen type methods
Abstract In this note we make a comparative study of the convergence orders for the Steffensen, Aitken and Aitken-Steffensen methods.…
Aitken-Steffensen-type methods for nonsmooth functions (III)
Abstract We provide sufficient conditions for the convergence of the Steffensen method for solving the scalar equation \(f(x)=0\), without assuming…
