This standard, designated FORTRAN 77, introduced many new statements into the language. In fact, the previous language standard FORTRAN 66 is a very small document and describes, what is in effect, a subset of most implementations of FORTRAN. For example, the WATFIV and WATFOR-11 implementations are based upon the IBM definition of FORTRAN-IV.
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 ]
As software development shifted from purely procedural programming (such as found in FORTRAN) towards more object-oriented constructs (such as found in C++), it became the practice to write the code for a single (public) class in a single file (the 'one class per file' convention).
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 ...
For more information on Fortran standards, a number or resources are available, such as the Wikipedia Fortran entry or the Fortran wiki page. The Intel Fortran package included the Intel Array Visualizer, a visualization tool for scientific formats such as FITS and netCDF , which can produce x-y plots, contour plots, and image plots, and save ...
Understanding the problem and associated programming requirements is necessary for choosing the language best suited for the solution." [ 17 ] From Meek & Heath: "The essence of the art of choosing a language is to start with the problem, decide what its requirements are, and their relative importance since it will probably be impossible to ...
The additional features of subsequent standards, up to Fortran 2023, are described in the Fortran 2023 standard document, ISO/IEC 1539-1:2023. [2] Some of its new features are still being implemented in compilers. [3] Details can also be found in a range of textbooks, for instance [4] [5] [6] and see the list at Fortran Resources.
Daniel D. McCracken (July 23, 1930 – July 30, 2011) was a computer scientist in the United States. He was a professor of Computer Sciences at the City College of New York, and the author of over two dozen textbooks on computer programming, with an emphasis on guides to programming in widely used languages such as Fortran and COBOL.
