Blitz++ is a C++ class library for scientific computing which provides performance on par with Fortran 77/90. It uses template techniques to achieve high performance. The current versions provide dense arrays and vectors, random number generators, and small vectors and matrices.

CLN is a library for computations with all kinds of numbers. It has a rich set of number classes: - Integers (with unlimited precision), - Rational numbers, - Floating-point numbers: Short float, Single float, Double float, Long float (with unlimited precision), - Complex numbers, - Modular integers (integers modulo a fixed integer), - Univariate polynomials. The subtypes of the complex numbers among these are exactly the types of numbers known to the Common Lisp language. Therefore CLN can be used for Common Lisp implementations, giving `CLN' another meaning: it becomes an abbreviation of "Common Lisp Numbers".

Dr. Geo is a GTK interactive geometry software. It allows one to create geometric figure plus the interactive manipulation of such figure in respect with their geometric constraints. It is useable in teaching situation with students from primary or secondary level.

This is eispack from research.att.com. I've cleaned up the Makefile, but it is otherwise the same. The package is described in: 1. Smith, B.T, Boyle, J.M, Dongerra, J.J., Garbow, B.S., Ikebe, Y., Klema, V.C., and Moler, C.B., Matrix Eigensystem Routines -- EISPACK Guide, Lecture Notes in Computer Science, Vol. 6, Second Edition, Springer-Verlag, New York, Heidelberg, Berlin, 1976 2. Garbow, B.S., Boyle J.M., Dongerra, J.J, and Moler C.B., Matrix Eigensystem Routines -- EISPACK Guide Extension, Lecture Notes in Computer Science, Vol. 51, Springer-Verlag, New York, Heidelberg, Berlin, 1977 As the package is in FORTRAN there are no include files for the library, and the only thing to install is the library itself.

ent applies various tests to sequences of bytes stored in files and reports the results of those tests. The program is useful for evaluating pseudorandom number generators for encryption and statistical sampling applications, compression algorithms, and other applications where the information density of a file is of interest.

fxt is a library package (coming as C++ source code) containing various algorithms for: - Fast Fourier Transform (FFT) incl. real-vlued, - multidimensional and weighted variants. - Fast Hartley Transform (FHT) - Number Theoretic Transform (NTT), Fast Walsh Transform. - Convolution (cyclic, linear and weighted), - correlation and power spectrum. - Fast Haar Transform, Fast Wavelet Transform - Mass storage convolution and fast multiplication routines. - Sine- and cosine transform (DCT, DST), Fast Z-Transform (FZT)

Gambit is a library of game theory software and tools for the construction and analysis of finite extensive and normal form games. Gambit is designed to be portable across platforms. Gambit includes: - A graphical user interface, based upon the wxWindows library, providing a common look-and-feel across platforms. - The Gambit Command Language, a scripting language with built-in primitives for constructing and analyzing games. - A library of C++ source code for representing games, suitable for use in other applications.

geg, a GTK+ Equation Grapher is a very simple utility for parsing and plotting 2D-Functions, eg f(x) = 3 + sin(x), and much more complicated functions. It was written with GTK+ and provides a neat, configurable user interface.

LAPACK95 is a Fortran 95 interface to the Fortran 77 LAPACK library. It improves upon the original user-interface to the LAPACK package, taking advantage of the considerable simplifications which Fortran 95 allows. The design of LAPACK95 exploits assumed-shape arrays, optional arguments, and generic interfaces. The Fortran 95 interface has been implemented by writing Fortran 95 ``wrappers'' to call existing routines from the LAPACK package. This interface can persist unchanged even if the underlying Fortran 77 LAPACK code is rewritten to take advantage of the new features of Fortran 95.

LAPACKE is a standard C language APIs for LAPACK, which introduces the following features[1]: - row-major and column-major matrix layout controlled by the first function parameter; - an implementation with working arrays (middle-level interface) as well as without working arrays (high-level interface); - input scalars passed by value; - error code as a return value instead of the INFO parameter.
