muParser is an extensible high performance math parser library. It is based on transforming an expression into a bytecode and precalculating constant parts of it.

Ceres Solver is a C++ library for modeling and solving large, complicated optimization problems. It is a feature rich, mature and performant library which has been used in production since 2010. Ceres Solver can solve two kinds of problems:

1. non-linear least squares problems with bounds constraints;

2. general unconstrained optimization problems.

SCOTCH is a set of programs and libraries which implement the static mapping and sparse matrix reordering algorithms developed within the SCOTCH project. Its purpose is to apply graph theory, with a divide and conquer approach, to scientific computing problems such as graph and mesh partitioning, static mapping, and sparse matrix ordering, in application domains ranging from structural mechanics to operating systems or bio-chemistry.

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.

DUNE, the Distributed and Unified Numerics Environment is a modular toolbox for solving partial differential equations (PDEs) with grid-based methods.

This is the iterative solver template library which provides generic sparse matrix/vector classes and a variety of solvers based on these classes. A special feature is the use of templates to exploit the recursive block structure of finite element matrices at compile time. Available solvers include Krylov methods, (block-) incomplete decompositions and aggregation-based algebraic multigrid.

AMD is a set of routines for ordering a sparse matrix prior to Cholesky factorization (or for LU factorization with diagonal pivoting).

The C code of lrslib implements the reverse search algorithm for vertex enumeration and convex hull problems. Its input file format is compatible with cddlib. All computations are done exactly in either multiple precision or fixed integer arithmetic. Output is not stored in memory, so even problems with very large output sizes can sometimes be solved.

The itex2MML utility is a stream filter. It takes text with embedded itex equations, converts the itex equations to MathML, and outputs the resulting text.

MiniZinc is a high-level modeling language for constraint satisfaction and optimization problems. Models are compiled to FlatZinc, a language understood by many solvers.

The C-library cddlib implements the Double Description Method of Motzkin et al. for generating all vertices (i.e. extreme points) and extreme rays of a general convex polyhedron given by a system of linear inequalities in arbitrary dimension. It can also be used for the converse operation of computing convex hulls.

This package contains a set of routines for computing the LDL' factorization of sparse, symmetric matrices. Its focus lies on concise code.

SuiteSparse is a suite of sparse matrix algorithms, including: UMFPACK, multifrontal LU factorization; CHOLMOD, supernodal Cholesky; SPQR, multifrontal QR; KLU and BTF, sparse LU factorization, well-suited for circuit simulation; ordering methods (AMD, CAMD, COLAMD, and CCOLAMD); CSparse and CXSparse, a concise sparse Cholesky factorization package; and many other packages.

This package contains all of the above-mentioned parts.

This package provides client-server SDK for Matrix.

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.

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

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 implements a storage provider for Synapse, enabling it to fetch and store media in Amazon S3.

Synapse is a reference "homeserver" implementation of Matrix from the core development team at matrix.org, written in Python/Twisted. It is intended to showcase the concept of Matrix and let folks see the spec in the context of a codebase and let you run your own homeserver and generally help bootstrap the ecosystem.

Pantalaimon is an end-to-end encryption aware Matrix reverse proxy daemon. Pantalaimon acts as a good man in the middle that handles the encryption for you. Messages are transparently encrypted and decrypted for clients inside of pantalaimon.

This package contains code used by Synapse, Sydent, and Sygnal.
