FORTRAN subroutines for mathematical operations on polynomial functions

Abstract

The paper presents FORTRAN subroutines that can perform mathematical operations involving polynomial functions both in symbolic and in exact numerical modes. These subroutines may be used to perform operations including addition, multiplication, differentiation and integration of polynomial functions. An illustrative example performing various mathematical operations on polynomials has been demonstrated using these subroutines and the results obtained have been found to be highly accurate. The subroutines should be useful to analysts who require exact (or high precision) solutions to problems having a large number of mathematical operations of polynomial functions, such as in analyses of beam-column and plate structures. © 1995.
