LAPACK was originally written in FORTRAN 77, but moved to Fortran 90 in version 3.2 (2008). [3] The routines handle both real and complex matrices in both single and double precision. LAPACK relies on an underlying BLAS implementation to provide efficient and portable computational building blocks for its routines. [2]: "
QUADPACK is a FORTRAN 77 library for numerical integration of one-dimensional functions; SLATEC is a FORTRAN 77 library of over 1400 general purpose mathematical and statistical routines. SOFA is a collection of subroutines that implement official IAU algorithms for astronomical computations. Both Fortran and C versions are available.
HSL, originally the Harwell Subroutine Library, is a collection of Fortran 77 and 95 codes that address core problems in numerical analysis.It is primarily developed by the Numerical Analysis Group at the Rutherford Appleton Laboratory with contributions from other experts in the field.
This Fortran library is known as the reference implementation (sometimes confusingly referred to as the BLAS library) and is not optimized for speed but is in the public domain. [ 3 ] [ 4 ] Most libraries that offer linear algebra routines conform to the BLAS interface, allowing library users to develop programs that are indifferent to the BLAS ...
SLATEC Common Mathematical Library is a FORTRAN 77 library of over 1,400 general purpose mathematical and statistical routines. The code was developed at US government research laboratories and is therefore public domain software.
QUADPACK is a FORTRAN 77 library for numerical integration of one-dimensional functions. [2] It was included in the SLATEC Common Mathematical Library and is therefore in the public domain. [3] The individual subprograms are also available on netlib. [4] The GNU Scientific Library reimplemented the QUADPACK routines in C.
The application area of the library focuses on physics research, in particular high energy physics, involving general mathematics, data analysis, detectors simulation, data-handling, numerical analysis, and others, applicable to a wide range of scientific problems. Many modules are written in the FORTRAN 77 language.
An important practical extension to FORTRAN 77 was the release of MIL-STD-1753 in 1978. [37] This specification, developed by the U.S. Department of Defense, standardized a number of features implemented by most FORTRAN 77 compilers but not included in the ANSI FORTRAN 77 standard. These features would eventually be incorporated into the ...
