ALGORITHM-737 - INTLIB - A PORTABLE FORTRAN-77 INTERVAL STANDARD-FUNCTION LIBRARY

INTLIB is meant to be a readily available, portable, exhaustively docu mented interval arithmetic library, written in standard Fortran 77. It s underlying philosophy is to provide a standard for interval operatio ns to aid in efficiently transporting programs involving interval arit hmetic. The model is the BLAS package, for basic linear algebra operat ions. The library is composed of elementary interval arithmetic routin es, standard function routines for interval data and values, and utili ty routines. The library can be used with INTBIS (Algorithm 681), and a Fortran 90 module to use the library to define an interval data type is available from the first author.
