libcmime is a lightweight mime library, written in C. It attempts to be a general library for parsing and creating mime email messages and is designed to provide an easy to use and easy to integrate interface for developers. libcmime is a pretty fresh project so the library is still in beta state and there will be early and frequent releases.

Gnome Gmail Notifier项目旨在提供一个稳定、高效的GTK+2.0应用程序，它可以定期地 检查用户gmail收件箱。 这个Notifier会作为系统托盘图标显示在GNOME2桌面上，当用户收到新邮件时，弹出一个 小气球通知。 - Florent Thoumie flz@FreeBSD.org

Provides a framework to perform Non-negative Matrix Factorization (NMF). The package implements a set of already published algorithms and seeding methods, and provides a framework to test, develop and plug new/custom algorithms. Most of the built-in algorithms have been optimized in C++, and the main interface function provides an easy way of performing parallel computations on multicore machines.

Algae is a programming language for numerical analysis. It was written in the Boeing Company to fulfill their need for a fast and versatile tool, capable of handling large systems. Algae has been applied to interesting problems in aerospace and related fields for more than a decade.

This is a port of Clp (Coin-or linear programming), which is an open-source linear programming solver written in C++. It is primarily meant to be used as a callable library, but a basic, stand-alone executable version is also included.

vector-space provides classes and generic operations for vector spaces and affine spaces in Haskell. It also defines a type of infinite towers of generalized derivatives. A generalized derivative is a linear transformation rather than one of the common concrete representations (scalars, vectors, matrices, etc).

libranlip is a C++ library created by G. Beliakov, which generates random variates with arbitrary Lipschitz-continuous densities via the acceptance / rejection method. The density should have a dimension of no more than about five. The user needs to supply the density function using a simple syntax, and then call the methods of construction and generation provided in libranlip.

GMP is a free library for arbitrary precision arithmetic, operating on signed integers, rational numbers, and floating point numbers. There is no limit to the precision except the ones implied by the available memory in the machine GMP runs on. GMP has a rich set of functions, and the functions have a regular interface. This port compiles libgmp using MinGW32.

This module is about the native floating point numerical data type. A floating point number is one of the types of datum that can appear in the numeric part of a Perl scalar. This module supplies constants describing the native floating point type, classification functions, and functions to manipulate floating point values at a low level.

Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments. It may also be used as a batch-oriented language.
