Numerical Algorithms Group (NAG) Workstation Library for IBM PC/XT/AT or compatible for sale. The NAG Workstation Library contains 171 documented routines covering 18 major areas including ordinary differential equations, curve and surface fitting, optimisation, linear algebra, time series and statistics. The NAG Workstation Library is a subset of the complete NAG Fortran Library. NAG was formed in 1970 and the routines in the library are 'tried and true'. SUMMARY OF LIBRARY CONTENTS: NUMBER OF ROUTINES Zeroes of polynomials 1 Roots of 1 or more transcendental equations 2 Summation of series 5 e.g. discrete Fourier transform Quadrature 5 e.g. 1 and 2 dimemsional integrals Ordinary differential equations 10 e.g. Runge-Kutta-Merson; Adams, Gear methods Curve and surface fitting 12 e.g. least-squares fits; fitted functions Minimizing or maximizing a function 8 e.g. quasi-Newton; Gauss-Newton; linear, nonlinear programming Matrix operations 5 e.g. LU factorizations Eigenvalues and eigenvectors 14 e.g. complex, Hermitian, real matrices Simultaneous linear equations 12 Calculations on statistical data 14 e.g. 2-way contingency table; F, t, Chi^2, Beta etc distributions Correlation and regression analysis 8 e.g. Pearson product moment; multiple linear regressions Random number generators 25 Nonparametric statistics 6 e.g. Sign, Wilcoxon, Mann-Whitney, Friedman tests Time series analysis 7 Sorting 2 Approximations of special functions 31 e.g. Exponential, sign, Fresnel integrals; Bessel, Kelvin functions; gamma, error functions Machine constants and utilites 5 The library comes with extnesive manuals that briefly cover the theoretical aspects of the particular algorithm as well as how to implement the algorithm. Also included are example programs (source code) that demonstrate use of each subroutine. LIBRARY FORMAT: The library is in object code compiled with the Microsoft Fortran 4.01 compiler. NAG will upgrade the libraries from MS Fortran 4.01 to 4.1 which will link with MS Fortran 5.0 object modules for $75. To date NAG does not provide a library compiled with MS Fortran 5.0. HARDWARE REQUIREMENTS: Needs minimum 500 KB memory, 5.25" high density floppy drive, 2.2MB of hard disk space. A math coprocessor will be used if present which will speed floating point operations but it is not required. PRICE: I purchased the NAG library about a year ago for the academic price of $495 (U.S). Non academic price is $795. I will sell the NAG library for the be$t offer over $400 (U.S.). Edwin Barkdoll barkdoll@cattell.psych.upenn.edu Edwin Barkdoll barkdoll@cattell.psych.upenn.edu

No guarantees on PC compatibility though, its just regular fortran code. No hand-holding either, just well commented code. Some of the goodies available are: LINPACK - Linear algebra routines EISPACK - Eigenvector/value routines FFTPACK - Fast Fourier transform routines MINPACK - Minimization routines and LOTS more. So how do you find out what's available and how to get it? Just send E-mail to: netlib@ornl.gov In your message just type: send index That's all. You then get mail back telling you how to get the software. Since a computer reads your mail and responds, it only takes (me) about 10 minutes to get a reply. Hope this helps, Patrick Mullhaupt (pmm) PS The ornl in the address stands for Oak Ridge National Laboratory
