GNU spreadsheet for X11 and terminals
`Oleo' has more than one user interface. The traditional `oleo'
environment shows a curses based (character mode) user interface.
A bare bones user interface based on the X Window System exists as of
version 1.6 which dates back to 1994. In 1998, development started for
a `motif' based user interface. It should be more user friendly than
the character based UI.
Fast, robust constructive solid geometry library
Carve is a C++ library designed to perform boolean operations between two
arbitrary polygonal meshes. The standard union and intersection operations are
supported, as are symmetric and asymmetric difference. It is also possible to
implement custom operations using Carve, allowing results to be formed from any
combination of inputs.
Carve supports a variety of inputs, including both closed and open surfaces,
faces with arbitrary edge counts and datasets with multiple disjoint,
embedded or touching surfaces. Carve can also interpolate arbitrary
values across faces, meaning that CSG operations need not discard colour,
texture coordinates or other data.
Generates plots and graphs from data (no X11 required)
Small, fast library to generate prime numbers in order
primegen is a small, fast library to generate prime numbers in
order. It generates the 50847534 primes up to 1000000000 in just 8
seconds on a Pentium II-350; it prints them in decimal in just 35
seconds.
primegen can generate primes up to 1000000000000000, although it
is not optimized for primes past 32 bits. It uses the Sieve of Atkin
instead of the traditional Sieve of Eratosthenes.
Utilities for handling IEEE 754 floating point special values
This python module implements constants and functions for working with
IEEE754 double-precision special values. It provides constants for
Not-a-Number (NaN), Positive Infinity (Inf), and Negative Infinity (-Inf),
as well as functions to test for these values.
Package for parallel (mpi) unstructured graph partitioning
ParMETIS is an MPI-based parallel library that implements a variety
of algorithms for partitioning unstructured graphs and for computing
fill-reducing orderings of sparse matrices. ParMETIS extends the
functionality provided by METIS and includes routines that are
especially suited for parallel AMR computations and large scale
numerical simulations. The algorithms implemented in ParMETIS are
based on the parallel multilevel k-way graph-partitioning algorithms
described in [KK95d], [KK96], [KK97], and the adaptive repartitioning
algorithms described in [SKK97a], [SKK97b], [SK+98], and [SKK98].
Package that produces combinations and permutations
A package that returns all the combinations and
permutations, without repitition, of a given set
and subset size. Associative arrays are preserved.
Numeric array manipulation extension module for Python
Numarray is a reimplementation of the original Python Numeric array
module that provides Python with capbilities similar to Matlab, IDL,
Octave, APL and other array-based languages. This version is still
in its early stages and is not yet the official replacement for
Numeric though we hope it will be before long. It is not fully
backwards compatible with Numeric, particularly with regard to the
C API.
Flexible calculator that behaves much like units(1)
Physcalc is a neat mathematical calculator that does conversions
from many different units in many forms, and is extremely flexible
as far as specifying math problems go. You can also add your own
types of conversions.
