Fortran (/ ˈ f ɔːr t r æ n /; formerly FORTRAN) is a third generation, compiled, imperative programming language that is especially suited to numeric computation and scientific computing.
GNU Fortran (GFortran) is an implementation of the Fortran programming language in the GNU Compiler Collection (GCC), an open-source and free software project maintained in the open-source programmer community under the umbrella of the GNU Project. It is the successor to previous compiler versions in the suite, such as g77.
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 ...
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. MINPACK, along with other similar libraries such as LINPACK and EISPACK , originated from the Mathematics and Computer Science Division Software (MCS) of ...
Simply Fortran is an Integrated Development Environment (IDE) for GNU Fortran (which currently implements FORTRAN 77, Fortran 90, Fortran 95, Fortran 2003 and Fortran 2008). [1] The project is maintained by the company Approximatrix, LLC .
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.

NASTRAN was designed from the beginning to consist of several modules. A module is a collection of FORTRAN subroutines designed to perform a specific task—processing model geometry, assembling matrices, applying constraints, solving matrix problems, calculating output quantities, conversing with the database, printing the solution, and so on.
