Abstract Partial differential approximants can accurately approximate functions of two variables, even when the only information available concerning the function is a finite number of terms in its power series expansion. They are particularly effective in the approximation of multisingular functions. After a brief review we present a library of FORTRAN 77 subroutines which generate and analyze partial differential approximants. A driver program which demonstrates the library's use is also included. ... Title of program: PARTIAL DIFFERENTIAL APPROXIMANT Catalogue Id: ABTW_v1_0 Nature of problem The approximation of a two-variable function known only through a finite number of terms in its power series expansion.
