HDF-EOS2 is a software library built on HDF4 which supports the construction of data structures used in NASA's Earth Observing System (Grid, Point and Swath).

CHOLMOD is a set of routines for factorizing sparse symmetrix positive definite matrices, updating/downdating sparse Cholesky factorizations and other related operations.

PDELab is a partial differential equations solver toolbox built on top of DUNE, the Distributed and Unified Numerics Environment.

Kissat is a bare-metal SAT-solver written in C. It is a port of CaDiCaL back to C with improved data structures, better scheduling of inprocessing and optimized algorithms and implementation.

bliss is a library for computing automorphism groups +and canonical forms of graphs. It has both a command line user interface as +well as C++ and C programming language APIs.

The General Cartographic Transformation Package (GCTP) is a system of software routines designed to permit the transformation of coordinate pairs from one map projection to another. The GCTP is the standard computer software used by the National Mapping Division for map projection computations.

The dozenal suite is a set of programs designed to assist with working in the dozenal (also called "duodecimal" or "base twelve") system. It includes number converters (dozenal-to-decimal and decimal-to-dozenal), an RPN calculator, a graphical calculator, a metric system converter (works with imperial, U.S. customary, SI metric, and the dozenal TGM), a pretty-printer for dozenal numbers, a date-and-time program, and a dozenal calendar programs, complete with events and to-dos.

Cbc (Coin-or branch and cut) is a mixed integer linear programming solver written in C++. It can be used as a library or as a standalone executable.

lp_solve is a mixed integer linear programming solver based on the revised simplex and the branch-and-bound methods.

ALUGrid is an adaptive, loadbalancing, unstructured implementation of the DUNE grid interface supporting either simplices or cubes.

Elemental is a modern C++ library for distributed-memory dense and sparse-direct linear algebra, conic optimization, and lattice reduction.

Arcane is a development environment for parallel numerical calculation code. It supports the architectural aspects of a calculation code, such as data structures for meshing and parallelism, as well as more environment-related aspects such as dataset configuration.

Matio is a library for reading and writing MAT files. It supports compressed MAT files, as well as newer (version 7.3) MAT files.

NOMAD is a C++ implementation of the mesh-adaptive direct search (MADS) algorithm, designed for difficult blackbox optimization problems. These problems occur when the functions defining the objective and constraints are the result of costly computer simulations.

Libqalculate is a multi-purpose cli desktop calculator and library. It provides basic and advanced functionality. Features include customizable functions, unit calculations, and conversions, physical constants, symbolic calculations (including integrals and equations), arbitrary precision, uncertainty propagation, interval arithmetic, plotting and a user-friendly cli.

CGLM is an optimised 3D maths library for graphics software based on the GLSL specifications.

It's similar to the original C++ GLM library but written in C99 and compatible with C89.

DUNE, the Distributed and Unified Numerics Environment is a modular toolbox for solving partial differential equations (PDEs) with grid-based methods. It supports the easy implementation of methods like Finite Elements (FE), Finite Volumes (FV), and also Finite Differences (FD).

This package contains the basic DUNE geometry classes.

ndim computes all kinds of volumes and integrals of monomials over such volumes in a fast, numerically stable way, using recurrence relations.

wxMaxima is a graphical user interface for the Maxima computer algebra system. It eases the use of Maxima by making most of its commands available through a menu system and by providing input dialogs for commands that require more than one argument. It also implements its own display engine that outputs mathematical symbols directly instead of depicting them with ASCII characters.

wxMaxima also features 2D and 3D inline plots, simple animations, mixing of text and mathematical calculations to create documents, exporting of input and output to TeX, and a browser for Maxima's manual including command index and full text searching.

METIS is a set of serial programs for partitioning graphs, partitioning finite element meshes, and producing fill-reducing orderings for sparse matrices. The algorithms implemented in METIS are based on the multilevel recursive-bisection, multilevel k-way, and multi-constraint partitioning schemes.

This package provides client-server SDK for Matrix.

Matrix nio is a multilayered Matrix client library. The underlying base layer doesn't do any network IO on its own, but on top of that is a full fledged batteries-included asyncio layer using aiohttp.

This package provides a Matrix<->WhatsApp puppeting bridge based on whatsmeow.

This package allows Synapse to use LDAP as a password provider. This lets users log in to Synapse with their username and password from an LDAP server.
