Coarray Fortran (CAF), formerly known as F--, started as an extension of Fortran 95/2003 for parallel processing created by Robert Numrich and John Reid in the 1990s. The Fortran 2008 standard (ISO/IEC 1539-1:2010) now includes coarrays (spelled without hyphen), as decided at the May 2005 meeting of the ISO Fortran Committee; the syntax in the Fortran 2008 standard is slightly different from ...
The codes for the different kind of matrices are reported below; the actual data are stored in a different format depending on the specific kind; e.g., when the code DI is given, the subroutine expects a vector of length n containing the elements on the diagonal, while when the code GE is given, the subroutine expects an n×n array containing ...
MINPACK is a library of FORTRAN subroutines for the solving of systems of nonlinear equations, or the least squares minimization of the residual of a set of linear or nonlinear equations. The NAG Fortran Library is a collection of mathematical and statistical routines for Fortran. NOVAS is a software library for astrometry-related numerical ...
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.
F retains the array features added in Fortran 90, and removes control statements that were made obsolete by structured programming constructs added to both FORTRAN 77 and Fortran 90. F is described by its creators as "a compiled, structured, array programming language especially well suited to education and scientific computing". [ 71 ]
Each subroutine in SLATEC is tagged as belonging to one of 13 subpackages. Some of these subpackages are also well known as free-standing FORTRAN subprogram libraries, including BLAS, EISPACK, FFTPACK, LINPACK and QUADPACK. The following table shows all subpackages and the number of subroutines they contain:
If the array abstraction does not support true negative indices (as for example the arrays of Ada and Pascal do), then negative indices for the bounds of the slice for a given dimension are sometimes used to specify an offset from the end of the array in that dimension. In 1-based schemes, -1 generally would indicate the second-to-last item ...
The Message Passing Interface (MPI) is a portable message-passing standard designed to function on parallel computing architectures. [1] The MPI standard defines the syntax and semantics of library routines that are useful to a wide range of users writing portable message-passing programs in C , C++ , and Fortran .
