Frontiers in Applied Mathematics, 7. Philadelphia, PA: SIAM, Society for Industrial and Applied Mathematics. xiv, 164 p. $ 22.50 (1990).
A software package for solving the plane elliptic differential equations in Cartesian coordinates is represented. This is not a book about numerical methods, here the author refers to the references. Only in the introduction he remarks, that the mathematical background is a finite element method.
The subroutines and their parameters are described in a very detailed manner. If necessary some examples are given. The lot of parameters, which can be modified by the user, is so great that a wide range of elliptic problems can be solved; several mesh refinements are possible too. But it seems that nowadays are better methods for producing user supplied routines than there. According to the possibilities of the modern computers the package contains some routines for the graphic representation and manipulation of the data. All subroutines are based on the computer language FORTRAN.
