Gmm++ is a generic C++ template library for sparse, dense and skyline
matrices. It is built as a set of generic algorithms (mult, add,
copy, sub-matrices, dense and sparse solvers ...) for any interfaced
vector type or matrix type. It can be view as a glue library allowing
cooperation between several vector and matrix types. However, basic
sparse, dense and skyline matrix/vector types are built in Gmm++,
hence it can be used as a standalone linear algebra library.
Interfacing a vector or matrix type means writing "traits" objects
called "linalg_traits", which describe their properties. The library
offers predefined dense, sparse and skyline matrix types.

syntax. It has several builtin functions for algorithmic number
theory like gcd, Jacobi symbol, Rabin probabilistic prime test,
continued fraction and quadratic sieve factorization, Pollard rho
factorization, etc.

Lens is an efficient, yet flexible, neural network simulator that runs on
a variety of platforms, is able to handle large, complex simulations, but
is also reasonably easy for novices to operate.

Move misc/gretl to math/gretl; add secondary category of finance
gretl is used in the mathematical analysis of time series,
and has a functionality that is similar to various statistical
and signal processing components of it++, octave, scilab,
R, numpy/scipy, etc. -- most of which are in the math
category. It should really be placed there, rather than
in misc. In recognition of the fact that it implements
some methods that are commonly (but not exclusively!) used
in econometrics, it should also be given a secondary listing
in finance. (In my opinion, however, it shouldn't be given
a primary listing in that category, because most of the
ports there deal with the nuts-and-bolts of accounting,
payment methods, taxes, and stock tracking. To my knowledge,
the only ports now in finance that remotely resemble gretl
are quantlib, xtrader, and qtstalker, all of which employ
simpler methods that are more specific to financial time
series than are the more general methods in gretl.

The JTS Topology Suite is an API of 2D spatial predicates and functions. It has
the following design goals:
* JTS conforms to the Simple Features Specification for SQL published by the
Open GIS Consortium
* JTS provides a complete, consistent, robust implementation of fundamental
2D spatial algorithms
* JTS is fast enough for production use
* JTS is written in 100% pure Java(TM)
* JTS is open source (under the LGPL license)

Wcalc is a powerful arbitrary-precision calculator. It has standard functions
(sin, asinh, logtwo, floor, etc), many pre-defined constants (pi, e, c, etc.),
variables, "active" variables, command history, and hex/octal/binary i/o,
conversions, and more.

moo is a simple calculator that accepts C-like syntax as input.
Calculations are done on expr, if given. Otherwise, the standard input is used.
Numbers can be entered in hexadecimal (0xbeef), decimal (1984), octal (007),
and binary (0b1001). All numerical operators (+, -, *, /, %), bit operators
(|, ^, &, ~, <<, >>), and logical operators (==, !=, <, >, <=, >=, !, &&, ||)
are supported.

Regression.pm is a multivariate linear regression package.
That is, it estimates the c coefficients for a line-fit of the type
y= c(0)*x(0) + c(1)*x1 + c(2)*x2 + ... + c(k)*xk
given a data set of N observations, each with k independent x variables
and one y variable. Naturally, N must be greater than k---and preferably
considerably greater. Any reasonable undergraduate statistics book will
explain what a regression is. Most of the time, the user will provide a
constant ('1') as x(0) for each observation in order to allow the
regression package to fit an intercept.

math/qd, a new port:
A Double-Double and Quad-Double Arithmetic library.
Double-double and quad-double numbers are unevaluated sum of
two and four IEEE doubles capable of representing 106 and 212 bits
of significand, respectively. The library is written in C++, taking full
advantage of operator overloading. C, Fortran 77, and Fortran 90 interfaces
are also provided.
This work was done at Lawrence Berkeley National Laboratory,
NERSC Division, Yozo Hida with Xiaoye S. Li and David H. Bailey.

Fast Artificial Neural Network Library is a free open source neural network
library, which implements multilayer artificial neural networks in C with
support for both fully connected and sparsely connected networks.
Cross-platform execution in both fixed and floating point are supported. It
includes a framework for easy handling of training data sets. It is easy to
use, versatile, well documented, and fast. PHP, C++, .NET, Ada, Python, Delphi,
Octave, Ruby, Pure Data and Mathematica bindings are available. A reference
manual accompanies the library with examples and recommendations on how to use
the library. A graphical user interface is also available for the library.

Msieve is a library and utility for factoring large integers using the most
powerful modern algorithms. It features a stable and very fast implementation
of a self-initializing multiple polynomial quadratic sieve (MPQS), plus a
highly experimental and unfinished number field sieve (NFS) implementation.
Primary design goals are speed, portability and ease of use. Msieve claims to
be the fastest implementation for factoring general inputs between 40 and 100
decimal digits.
