CERN Program Library
The CERN Program Library or CERNLIB is a collection of FORTRAN77 libraries and modules, maintained by CERN. Its content ranges from more specialized data analysis of high energy physics to general purpose numerical analysis. Lower-level parts of the CERN Program Library are most prominently used by the data analysis software PAW and the detector simulation framework GEANT (which themselves are contained in the CERN Program Library).
The major fields covered by the libraries contained therein are:
- Detector simulation
- Elementary particle data
- Graphics and plotting
- Hadronic event generation
- I/O and structured data storage
- Numerical analysis
- Statistics and data analysis
Besides legacy software dependency, for newer softwares written in C++, CERNLIB is mostly superseded by ROOT.
