SpamAssassin is a mail filter which attempts to identify spam using text
analysis and several internet-based realtime blacklists.
Using its rule base, it uses a wide range of heuristic tests on mail
headers and body text to identify "spam", also known as unsolicited
commercial email.
Once identified, the mail can then be optionally tagged as spam for later
filtering using the user's own mail user-agent application.
Additional drop-in rule sets are available at

ARPACK software is capable of solving large symmetric, nonsymmetric, and
generalized eigenproblems. The software is designed to compute a few (k)
eigenvalues with user-specified features, such as those of largest real part
or largest magnitude. Storage requirements are on the order of n*k locations,
and no auxiliary storage is required. A set of numerically orthogonal Schur
basis vectors for the desired k-dimensional eigen-space is computed.
Numerically accurate eigenvectors are available on request.
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.
Chryzodus is a cross-platform graphical program drawing
beautiful and colorful chryzodes.
If you do not know what chryzodes are, take a look at
http://www.chryzode.org/. Then you will be able to explore
the world of chryzodes by yourself using Chryzodus.
But one does not even need to know much about chryzodes
to use Chryzodus and see beautiful images appear on the screen!
clRNG
a library for uniform random number generation in OpenCL.
Streams of random numbers act as virtual random number generators.
They can be created on the host computer in unlimited numbers, and
then used either on the host or on computing devices by work items
to generate random numbers. Each stream also has equally-spaced
substreams, which are occasionally useful. The API is currently
implemented for four different RNGs, namely the MRG31k3p, MRG32k3a,
LFSR113 and Philox-4x32-10 generators.
Gnuplot is a portable multi-platform command-line driven graphing utility. It
was originally created to allow scientists and students to visualize
mathematical functions and data interactively, but has grown to support many
non-interactive uses such as web scripting. It is also used as a plotting engine
by third-party applications like Octave. Gnuplot has been supported and under
active development since 1986.
This port installs extra files for TeX terminals (latex, epslatex, Tikz, etc).
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.

FaCiLe is a constraint programming library on integer and integer set
finite domains written in OCaml. It offers all usual facilities to create
and manipulate finite domain variables, arithmetic expressions and
constraints, built-in global constraints and search and optimization goals.
FaCiLe allows as well to build easily user-defined constraints and goals,
making pervasive use of OCaml higher-order functionals to provide a simple
and flexible interface for the user.
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 lssa.
A package implementing tools to compute spectral decompositions of
irregularly-spaced time series. Currently includes functions based off the
Lomb-Scargle periodogram and Adolf Mathias' implementation for R and C (see
http://www.jstatsoft.org/v11/i02).

This is msh.
Package for creating and managing triangular and tetrahedral meshes for
Finite Element or Finite Volume PDE solvers. Uses a mesh data structure
compatible with pdetool. Relies on gmsh for unstructured mesh generation.
