Peter Benner Fortran 77 code
SLICOT Subroutine Library in Control Theory, Parallel Library in Control (PLiC) for large-scale time-invariant linear control systems in state-space form on parallel distributed computers, eigenvalues of Hamiltonian Matrices, subroutines for compressing a symmetric or triangular matrix to packed storage mode or to unpack a packed array to full storage mode, benchmark examples of discrete-time algebraic Riccati equations, benchmark examples of continuous-time algebraic Riccati equations.
PNNL Fortran Library (FLIB)
Mainly non-numeric library for handling text, including parsing, accessing the command line, dates and times, and some random number generation.
PORT Mathematical Subroutine Library
Collection of Fortran 77 routines that address many traditional areas of mathematical software, including approximation, ordinary and partial differential equations, linear algebra and eigensystems, optimization, quadrature, root finding, special functions, and Fourier transforms, but excluding statistical calculations. PORT stands for Portable, Outstanding, Reliable, and Tested.
Practical Guide to Splines
Code from the book by Carl de Boor.
Prime
Counts prime numbers.
Problem Generators
Generators for linear ordering and clustering problems, by John E. Mitchell.
PSIDE (Parallel Software for Implicit Differential Equations)
Code for solving implicit differential equations on shared memory parallel computers, by Jacques J.B. de Swart, Walter M. Lioen, and Wolter A. van der Veen.
PsSchur
Computes the periodic real Schur decomposition of a matrix product. By Kurt Lust.
Public Domain Aeronautical Software (PDAS)
Programs for aeronautical engineering, many from NASA or USAF, complete with public domain source code, instructions and sample cases on CD-ROM. [Commercial]
RIM: Computing the Acoutic Field Surrounding a Vibrating Plate
Shareware by Stephen Kirkup.
Robert Parker Software
Plotxy allows the user, either interactively at the terminal, or though scripts, to create simple graphs in the x-y plane. It gives the user complete of control of many aspects of the graph (eg, picture size, text font, line weight, math and Greek symbols, color palette specification). Color produces contour diagrams, with Contour producing a B/W equivalent. Magmap maps magnetic field components using spherical harmonic representations. PSD estimates the Power Spectral Density of a time series. Cross calculates frequency domain functions from a pair of input time series.
Roland Schmehl's Fortran parser
Another parser of Fortran code.
Rule Learning
Code estimates the population rule learning model on experimental data.
Selected Publications and Unpublished Software of Patrick Keast
Code for partial differential equations, quadrature, and the solution of linear systems, with associated papers.
ShareBufferWin32
Easy Inter-Process Shared Memory Communication Utilities for Win32 using a simple Fortran 77-style interface. Written for Compaq Visual Fortran by Gary Scott.
Software by P.B. Stark and Coauthors
Bvls.f solves least-squares problems with bounds on the variables. Qr.f computes QR decompositions in a stable way. Sbl1.f finds bounds on linear functionals of an n-vector subject to an l1 constraint on the misfit to a set of linear relations, and linear inequality constraints on the variables. Sbvq.f finds bounds on linear functionals of an n-vector subject to a quadratic constraint on the misfit to a set of linear relations, and linear inequality constraints on the variables.
SophtwareKodeWerks
Fortran 77 codes to solve the quadratic equation, solve a nonlinear equation using the Newton-Raphson method, fit a simple linear regression, and solve a system of equations using Gaussian elimination.
Special Functions code
Routines to accompany the book "Computation of Special Functions", by Shanjie Zhang and Jianming Jin.
Starlink
Astronomy software, much in Fortran.
