New version announcement for TaylUR, an arbitrary-order diagonal automatic differentiation package for Fortran 95

. co m p - ph ] 1 6 Ja n 20 06 TaylUR , an arbitrary - order diagonal automatic differentiation package for Fortran 95

We present TaylUR, a Fortran 95 module to automatically compute the numerical values of a complex-valued function's derivatives with respect to several variables up to an arbitrary order in each variable, but excluding mixed derivatives. Arithmetic operators and Fortran intrinsics are overloaded to act correctly on objects of a defined type taylor, which encodes a function along with its first ...

TaylUR 3, a multivariate arbitrary-order automatic differentiation package for Fortran 95

s . co m p - ph ] 2 9 Ju n 20 05 TaylUR , an arbitrary - order automatic differentiation package for Fortran 95

We present TaylUR, a Fortran 95 module to automatically compute the numerical values of a complex-valued function's derivatives w.r.t. several variables up to an arbitrary order in each variable, but excluding mixed derivatives. Arithmetic operators and Fortran 95 intrinsics are overloaded to act correctly on objects of defined type taylor, which encodes a function along with its first few deri...

On the Automatic Differentiation of Computer Programs

-4utomatic differentiation (AD) is a methodology for developing sensitivity-enhanced versions of arbitrary computer programs. In this paper, we provide some background information on AD and address some frequently asked questions. We introduce the ADIFOR and ADIC tools for the automatic differentiation of Fortran 77 and ANSI-C programs, respectively, and give an example of applying ADIFOR in th...

DNAD, a simple tool for automatic differentiation of Fortran codes using dual numbers

DNAD (dual number automatic differentiation) is a simple, general-purpose tool to automatically differentiate Fortran codes written in modern Fortran (F90/95/2003) or legacy codes written in previous version of the Fortran language. It implements the forward mode of automatic differentiation using the arithmetic of dual numbers and the operator overloading feature of F90/95/2003. Very minimum c...
