PCOMP


Summary:
PCOMP implements the forward and reverse mode for functions written in a FORTRAN-like modeling language, a subset of FORTRAN with a few extensions. First- and second-order derivatives are supported.

Features:
PCOMP reads symbolically defined nonlinear functions that are composed of standard elementary functions, and precompiles them. Subsequently function and, in particular, derivative values up to order two can be computed directly, i.e. without numerical approximation or symbolic differentiation. Alternatively FORTRAN-code for function and gradient evaluation can be generated automatically by PCOMP.
