Fortran is a language used extensively in the scientific community due to its suitability for numerical computation. Particularly attractive is its intuitive array notation, which makes writing fast vectorised computations easy. Despite its age, Fortran is still actively developed, with numerous implementations, including GNU, Intel, PGI and Cray. GNU Makefile standards. The GNU Makefile Standards Document (seeSection “Makefile Conventions” inThe GNU Coding Standards) is long, complicated, and subject to change.
