Um algoritmo algebrico para isolar zeros polinomiais complexos
Camargo, Maria Angelica de Oliveira; Trevisan, Vilmar; Claudio, Dalcidio Moraes (1995) [Artigo de periódico]O presente trabalho trata do problema de isolar zeros de polinômios • complexos. Muitos algoritmos calculam zeros polinomiais, a partir de regiões iniciais disjuntas, cada uma contendo um único zero. Entre tanto o problema ... -
An interval fixed point theorem
Oliveira, Paulo Werlang de; Claudio, Dalcidio Moraes (1996) [Artigo de periódico]In this paper we will present an interval version to the Fixed Point Theorem. Such theorem offers a practical method (the 'sucessive ap proximations method') which serves to the interval fixed point equa tion root compute. ... -
Computational arithmetic : an updated view
Diverio, Tiaraju Asmuz; Claudio, Dalcidio Moraes (1996) [Artigo de periódico]'This paper begins with a review of the fioating-point system, where fioating-point numbers are characterized. It reveals the need of a stan dard in order to solve the problem of production of different results in different ... -
High performance with high accuracy laboratory
Diverio, Tiaraju Asmuz; Navaux, Philippe Olivier Alexandre; Claudio, Dalcidio Moraes; Holbig, Carlos Amaral; Fernandes, Ursula Adriane Lisboa; Sagula, Rafael Linden (1996) [Artigo de periódico]ln order to obtain high performance with high accuracy in the so lution of scientific computational problems, a computational tool has been developed, called High Performance with High Accuracy Labora tory. ln this paper ... -
Inclusion methods for real and complex functions in one variable
Claudio, Dalcidio Moraes; Rump, Siegfried M. (1995) [Artigo de periódico]A new method is discussed for obtaining a validated inclusion of a zero of a real or complex function in one variable. The method is given by means of a sufficient criterion which can be tested on a digital computer. The ... -
A two-sided method for nonlinear equations with cubic convergence
Claudio, Dalcidio Moraes; Zingano, Paulo Ricardo de Avila (1989) [Artigo de periódico]A two-sided method for finding a zero of 'a real-valued function on a given interval is presented and its convergence features are analysed, This method combines ih a simple way the well known schemes of Newton Raphson and ...
