The Altran system for rational function manipulation — a survey

Posted

Altran is a complete system for symbolic computation with rational functions in several variables with integer coefficients. It has been designed and implemented to handle large problems with ease and efficiency. Considerable effort has been spent to ensure a minimum amount of machine dependence in the implementation, thus permitting the system to be installed quickly and easily on a variety of computing machines. In this paper a brief description of the language, run time data structures, and implementation is given.
