Deal.II is a C++ program library targeted at the computational solution of partial differential equations using adaptive finite elements. The main aim of deal.II is to enable rapid development of modern finite element codes, using among other aspects adaptive meshes and a wide array of tools often used in finite element programs.

HiGHS provides serial and parallel solvers for large-scale sparse linear programming (LP), mixed-integer programming (MIP), and quadratic programming (QP) models

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.

This library provides portable Arbitrary-precision unsigned integer arithmetic in C, for calculating with large numbers. Basic arithmetic (+, -, *, /, %) and bitwise operations (&, |, ^. <<, >>) plus increments, decrements and comparisons are supported.

NetCDF is an interface for scientific data access and a software library that provides an implementation of the interface. The netCDF library defines a machine-independent format for representing scientific data. Together, the interface, library, and format support the creation, access, and sharing of scientific data.

This package provides a C++ interface to the NetCDF library for scientific data storage.

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.

CryptoMiniSat is an incremental SAT solver with both command line and library (C++, C, Python) interfaces. The command-line interface takes a CNF as an input in the DIMACS format with the extension of XOR clauses. The library interfaces mimic this and also allow incremental solving, including assumptions.

Ruy is a matrix multiplication library. Its focus is to cover the matrix multiplication needs of neural network inference engines. Its initial user has been TensorFlow Lite, where it is used by default on the ARM CPU architecture.

HDF5 is a suite that makes possible the management of extremely large and complex data collections.

SMTInterpol is an SMT solver, that can compute Craig interpolants for various theories.

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.

SuiteSparse is a suite of sparse matrix algorithms. This package contains a library with common configuration options.

Qalculate-gtk is the GTK frontend for libqalculate. It is a multi-purpose GUI desktop calculator. 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.

The dune-functions module provides an abstraction layer for global finite element functions. Its two main concepts are functions implemented as callable objects, and bases of finite element spaces.

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

Arccon is part of the Arcane framework, providing core functionality for the Arcane development platform.

This package provides a Wolfram language lexer for Pygments.

SuperLU is a general purpose library for the direct solution of large, sparse, nonsymmetric systems of linear equations on high performance machines. The library is written in C and is callable from either C or Fortran. The library routines perform an LU decomposition with partial pivoting and triangular system solves through forward and back substitution. The library also provides threshold-based ILU factorization preconditioners.

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.

This package provides a Django front end for Mathics3.

SLEEF (SIMD Library for Evaluating Elementary Functions) is a library that implements vectorized versions of all C99 real floating point math functions. It can utilize SIMD instructions that are available on modern processors.

BLIS is a portable software framework for instantiating high-performance BLAS-like dense linear algebra libraries. The framework was designed to isolate essential kernels of computation that, when optimized, immediately enable optimized implementations of most of its commonly used and computationally intensive operations. While BLIS exports a new BLAS-like API, it also includes a BLAS compatibility layer which gives application developers access to BLIS implementations via traditional BLAS routine calls.

LAPACK is a Fortran 90 library for solving the most commonly occurring problems in numerical linear algebra.
