LabPlot is a program for two- and three-dimensional graphical presentation of data sets and functions. LabPlot allows you to work with multiple plots which each can have multiple graphs. The graphs can be produced from data or from functions.

Library of elementary mathematical functions, probability and elliptic integrals in 80-bit (x86) or 128-bit long double precision.

The MPFR library is a C library for multiple-precision floating-point computations with exact rounding (also called correct rounding). It is based on the GMP multiple-precision library. The main goal of MPFR is to provide a library for multiple-precision floating-point computation which is both efficient and has a well-defined semantics. It copies the good ideas from the ANSI/IEEE-754 standard for double-precision floating-point arithmetic (53-bit mantissa).

librsb is a library for sparse matrix computations featuring the Recursive Sparse Blocks (RSB) matrix format. This format allows cache efficient and multi-threaded (that is, shared memory parallel) operations on large sparse matrices. The most common operations necessary to iterative solvers are available, e.g.: matrix-vector multiplication, triangular solution, rows/columns scaling, diagonal extraction / setting, blocks extraction, norm computation, formats conversion. The RSB format is especially well suited for symmetric and transposed multiplication variants. Most numerical kernels code is auto generated, and the supported numerical types can be chosen by the user at build time. librsb implements the Sparse BLAS standard, as specified in the BLAS Forum documents.

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 io. Input/Output in external formats.

Functions for Maximum Likelihood (ML) estimation and non-linear optimization, and related tools. It includes a unified way to call different optimizers, and classes and methods to handle the results from the ML viewpoint. It also includes a number of convenience tools for testing and developing your own models.

R-cran-miscTools is miscellaneous tools and utilities for R.

Calcoo is a scientific calculator designed to provide maximum usability. The features that make Calcoo better than (at least some) other calculator programs are: * Bitmapped button labels and display digits to improve readability. * No double-function buttons. * Undo/redo buttons. * Copy/paste interaction with X clipboard. * Both RPN (reverse Polish notation) and algebraic modes are available. * Tick marks to separate thousands. * Two memory registers with displays. * Displays for Y, Z, and T registers. * It is a purely scientific calculator. Features that Calcoo lacks: * Statistical mode. * HEX mode.

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.

Aspcud is a solver for package dependencies. A package universe and a request to install, remove, or upgrade packages have to be encoded in the CUDF format. Such a CUDF document can then be passed to aspcud along with an optimization criteria to obtain a solution to the given package problem.
