This is the port of e, a tiny expression evaluator.

BlockSolve95 is a scalable parallel software library primarily intended for the solution of sparse linear systems that arise from physical models, especially problems involving multiple degrees of freedom at each node. For example, when the finite element method is used to solve practical problems in structural engineering, each node typically has two to five degrees of freedom; BlockSolve95 is designed to take advantage of problems with this type of local structure. BlockSolve95 is also reasonably efficient for problems that have only one degree of freedom associated with each node, such as the three- dimensional Poisson problem. BlockSolve95 is general purpose; we do not require that the matrices have any particular structure other than being sparse and being symmetric in structure (but not necessarily in value).

Cadabra is a symbolic computer algebra system (CAS) designed specifically for the solution of problems encountered in field theory. It has extensive functionality for tensor computer algebra, tensor polynomial simplification including multi-term symmetries, fermions and anti-commuting variables, Clifford algebras and Fierz transformations, component computations, implicit coordinate dependence, multiple index types and many more. The input format is a subset of TeX.

Calc is an interactive calculator which provides for easy large numeric calculations, but which also can be easily programmed for difficult or long calculations. It can accept a command line argument, in which case it executes that single command and exits. Otherwise, it enters interactive mode. There are a great number of pre-defined functions. The calculator can calculate transcendental functions, and accept and display numbers in real or exponential format. The calculator also knows about complex numbers.

Entropy is a program that will calculate the entropy of a given set of data. This program is mainly used to benchmark the efficiency of existing or developing compression algorithms.

From the README: calctool - README - November 1989. This is V2.4 of a simple desktop calculator. This version works under X11, XView and dumb tty terminals. It is almost visually identical to V2.1 which was released in August 1988, but internally most of the code has been reworked to include a level of graphics abstraction, to make porting this code to other window systems a trivial task. V2.4 includes display in scientific notation, color icons, a correct factorial function and fixes for a few minor bugs. It introduces the new versions for XView, X11, MGR and dumb terminals. New functions include hyperbolic and inverse hyperbolic trigonometrical functions, register exchange, constants and the input of numbers in exponential notation. You can also have a .calctoolrc file in your home directory, which can define upto ten new values for constants, and ten function definitions which are used in conjunction with the FUN key.

This package accompanies J. Fox, An R and S-PLUS Companion to Applied Regression, Sage, 2002. The package contains mostly functions for applied regression, linear models, and generalized linear models, with an emphasis on regression diagnostics, particularly graphical diagnostic methods. There are also some utility functions. With some exceptions, I have tried not to duplicate capabilities in the basic distribution of R, nor in widely used packages. Where relevant, the functions in car are consistent with na.action = na.omit or na.exclude.

Eval is a full featured floating point expression evaluator that can assign variables, has many built-in functions and constants, allows input and output in any number base, and uses a C-like syntax for expression evaluation. Full ANSI C source is included and easily portable to other platforms. Author: Will Menninger This version comes with readline support.

The octave-forge package is the result of The GNU Octave Repositry project, which is intended to be a central location for custom scripts, functions and extensions for GNU Octave. contains the source for all the functions plus build and install scripts. This is cgi. Common Gatway Interface for Octave.
