ARPACK-NG is a collection of Fortran77 subroutines designed to solve large scale eigenvalue problems.

This package provides a Cython interface to the C++ library primecount.

Qhull computes the convex hull, Delaunay triangulation, Voronoi diagram, halfspace intersection about a point, furthest-site Delaunay triangulation, and furthest-site Voronoi diagram. The source code runs in 2-d, 3-d, 4-d, and higher dimensions. Qhull implements the Quickhull algorithm for computing the convex hull. It handles roundoff errors from floating point arithmetic. It computes volumes, surface areas, and approximations to the convex hull.

Qhull does not support triangulation of non-convex surfaces, mesh generation of non-convex objects, medium-sized inputs in 9-D and higher, alpha shapes, weighted Voronoi diagrams, Voronoi volumes, or constrained Delaunay triangulations.

OpenLibm is an effort to have a high quality, portable, standalone C mathematical library (libm). It can be used standalone in applications and programming language implementations. The project was born out of a need to have a good libm for the Julia programming language that worked consistently across compilers and operating systems, and in 32-bit and 64-bit environments.

The dSMFT package speeds up Fast Mersenne Twister generation by avoiding the expensive conversion of integer to double (floating point). dSFMT directly generates double precision floating point pseudorandom numbers which have the IEEE Standard for Binary Floating-Point Arithmetic (ANSI/IEEE Std 754-1985) format. dSFMT is only available on the CPUs which use IEEE 754 format double precision floating point numbers.

This DUNE module provides interface and implementation for shape functions defined on the DUNE reference elements. In addition to the shape function, interpolation operators and special keys are provided which can be used to assemble global function spaces on finite-element grids.

Numdiff compares files line by line and field by field, ignoring small numeric differences and differences in numeric formats.

This is a filter for HDF5 that uses the Blosc compressor; by installing this filter, you can read and write HDF5 files with Blosc-compressed datasets.

This is a C version of the minpack minimization package. It has been derived from the fortran code using f2c and some limited manual editing. Extern C linkage permits the package routines to be called from C++.

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.

CAMD is a set of routines for ordering a sparse matrix prior to Cholesky factorization (or for LU factorization with diagonal pivoting). It is a variant of AMD which has the the option to apply constraints to the ordering.

This package provides a range of SAT solvers, including the sequential lingeling and its parallel variants plingeling and treengeling. A bounded model checker is also included.

Mongoose is a library for graph partitioning by computing edge cuts using a coarsening and refinement framework.

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

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.

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.

Fast Downward is a portfolio-based planning system that supports the propositional fragment of PDDL2.2.

Giza is a lightweight scientific plotting library built on top of cairo that provides uniform output to multiple devices.

This is a header-only C++ library for calculating analytical derivatives and taylor expansions of composite functions.

Z3 is a theorem prover and satisfiability modulo theories (SMT) solver. It provides a C/C++ API, as well as Python bindings.

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

Gnuplot is a portable command-line driven graphing utility. It was originally created to allow scientists and students to visualize mathematical functions and data interactively, but has grown to support many non-interactive uses such as web scripting. It is also used as a plotting engine by third-party applications like Octave.

The Java HDF5 Interface (JHI5) uses the Java Native Interface to wrap the HDF5 library, which is implemented in C.

PETSc, the Portable, Extensible Toolkit for Scientific Computation, is a suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations. It employs the MPI standard for all message-passing communication. petsc4py provides Python bindings to almost all functions of PETSc.
