Static C++ library collecting functions, variables, and classes for application in scientific codes.

• Integration: Numerical integration / quadrature (for both one- and multi-dimensional integrals).
• Linear_Algebra: Basic linear algebra functionality (vectors and matrices).
• Natural_Units: A simple implementation of natural units.
• Numerics: Various special functions and numerical algorithms (interpolation, root finding, multidimensional minimization).
• Special_Functions: Implementation of various functions.
• Statistics: Includes PDFs and CDFs for a number of distributions, sampling techniques, rudimentary data analysis, and Kernel density estimation.
• Utilities: Some useful functions, that don't fit anywhere else. (Progress bars, import and export of data from files,...)

• The unit tests are set up with the googletest framework, which is downloaded and installed automatically via CMake.
• The numerical integration methods rely partially on boost.
• The Configuration class uses the library libconfig. (If libconfig is not installed on the system, it will be downloaded and locally installed in /external/ via CMake.)

An example on how to include libphysica into your CMake build can be found in this repository, a C++ template code which is built with CMake and automatically downloads and includes this library during the build.
