Related Projects

Several noteworthy related projects:

- GSL - The GNU Scientific Library

The first truly free, ANSI-compliant, fully-tested, and well-documented scientific computing library. The GSL is located at http://www.gnu.org/software/gsl , and the manual is available at

http://www.gnu.org/software/gsl/manual/html_node/ . Many GSL routines are included and reworked in O2scl (the corresponding classes begin with the`gsl_`

prefix) and O2scl was specifically designed to be used with GSL. GSL is a must-have for most serious numerical work in C or C++ and is required for installation of O2scl . See also Galassi09 . - HDF - Hierarchical Data Format, (http://www.hdfgroup.org)

A library developed for file I/O of scientific data. Contains C, C++, FORTRAN and Java APIs, several command-line tools, and a longstanding active community of users. - Boost - (http://www.boost.org)

Free (license is compatible with GPL) peer-reviewed portable C++ source libraries that work well with the C++ Standard Library. Boost also contains uBlas, for linear algebra computing. - CERNLIB - (http://cernlib.web.cern.ch/cernlib/mathlib.html)

The gold standard in FORTRAN computing libraries. Several CERNLIB routines are rewritten completely in C++ and included in O2scl (they begin with the`cern_`

prefix). - LAPACK and ATLAS - The gold standard for linear algebra

Available at http://www.netlib.org/lapack and http://www.netlib.org/atlas . See also http://www.netlib.org/clapack . - QUADPACK - FORTRAN adaptive integration library, http://www.netlib.org/quadpack

This is the library on which the GSL integration routines are based (prefix`gsl_inte_`

). - GNU Units - Unit conversion utility from http://www.gnu.org/software/units/ . This utility can be used used by o2scl::convert_units in O2scl to perform unit conversions.
- Eigen - (http://eigen.tuxfamily.org)

A linear algebra library in C++. Eigen is licensed under MPLv2. - Armadillo - (http://arma.sourceforge.net)

A linear algebra library in C++. Armadillo is licensed under MPLv2. - Function Parser - (http://warp.povusers.org/FunctionParser/)

Free (LGPL3) class to parse and evaluate a mathematical expression stored in a string. Function Parser version 4.5 is included with O2scl in the directory`src/fparser`

. - FLENS - (http://flens.sourceforge.net)

A C++ library with object-oriented linear algebra types and an interface to BLAS and LAPACK. - MESA - Modules for Experiments in Stellar Astrophysics, (http://mesa.sourceforge.net)

An excellent FORTRAN library with accurate low-density equations of state, interpolation, opacities and other routines useful in stellar physics. Work is currently under way to rewrite some of the MESA routines in C/C++ for O2scl . Licensed with LGPL (not GPL). - OOL - Open Optimization Library (http://ool.sourceforge.net)

Constrained minimization library designed with GSL in mind. The O2scl constrained minimization classes are derived from this library, though OOL appears not to be under current development. Constrained Minimization . - Root - CERN's new C++ analysis package (http://root.cern.ch)

A gargantuan library for data analysis, focused mostly on high-energy physics. Their histograms, graphics, file I/O and support for large data sets is particularly good.
