Fortran Resources (Lahey)
A collection of links provided by a vendor of Fortran compilers.
Fortran78 Test Suite
Product of the NIST Information Technology Laboratory (ITL). It is used to determine, insofar as is practical, the degree to which a Fortran processor conforms to FIPS Fortran.
Fortran Tools by Nelson Beebe
Dcl2inc postprocesses ftnchek .dcl files to create separate include files; dtosstod converts Fortran floating-point precision; fpp is a reversible Fortran preprocessor; lprsf3 is a filter to print Fortran and SFTRAN3 files with boldface keywords; and pretty is a Fortran 66 prettyprinter.
Free Fortran Software
A collection of useful links from the Fortran Market.
Free Software (of Craig C. Douglas)
Fortran and C codes for fast matrix multiplication and multigrid solution of PDEs.
Fundamentals of Numerical Computing
Fortran 90 codes from book by Lawrence Shampine, Richard Allen, and Steven Pruess.
FXDR
Library by David W. Pierce that allows calls to the XDR (eXternal Data Representation) routines from Fortran.
GAMS : Guide to Available Mathematical Software
Guide to mathematical software in Fortran held at a small number of US government establishments. Some sources are in commercial libraries and are not directly accessible. The code is of a uniformly high quality but usually old; there may be more recent and better algorithms available.
GBYTES/SBYTES Library
Packages to handle binary unpacking and packing, in Fortran 77 and 90.
G77_i386_fpe_demo
Demonstrates handling of floating point exceptions under g77/i386/Linux. By Tom Crane.
Gridpak
Package for curvilinear orthogonal grid generation, which creates an orthogonal grid when provided with boundary information.
H. D. Knoble's Collection of Fortran Algorithms
Sourcecode of programs, mostly of a tutorial nature.
Hello, World
Example of simple program in Fortran.
Helmholtz
Fortran 90 code to solve the Diffusion-Advection-Reaction equation in 2D.
High Performance Finite Elements
Fortran 77 and 90 codes.
High Performance Fortran Applications Software Catalog
Links to fragments, which are very short codes or code fragments to demonstrate the language features and constructs, kernels, which are short self-contained codes chosen as representative of particular application algorithms and their language feature requirements, and full applications codes, not necessarily stored in full locally, but registered here with relevant pointers given to the code owner/contact person.
Hompack90
Suite of Fortran 90 subroutines by Layne T. Watson for solving nonlinear systems of equations by homotopy methods. There are subroutines for fixed point, zero finding, and general homotopy curve tracking problems, utilizing both dense and sparse Jacobian matrices, and implementing three different algorithms: ODE-based, normal flow, and augmented Jacobian.
Image Estimation by Example
Fortran 90 code of Jos Claerbout.
Input Routines
Fortran 90 module by Andy Stone that parses input lines into 'words', and routines that read a 'word' and translate it into a specified form, usually an integer or double-precision number. In conjunction with a simple CASE structure this provides a powerful and flexible method for organising data input. The package includes documentation, and an example program and data file as illustrations of the ways in which the module can be used to organise data. [gzipped tar file].
Introducing Fortran 95
Code from the book by Ian Chivers and Jane Sleightholme.
