Abstract:

A FORTRAN program is described by which systematically better approximants to a given real-valued function fT over 0 or T or infinity can be obtained. The program automatically generates these approximants once the user has provided the first K coefficients of the small T expansion for fT and the first M coefficients of the large T expansion. A punched FORTRAN deck for the desired approximant to fT is generated. Author
