fortran 77 tutorial

fortran 77 tutorial (nearly identical versions available at several sites online) 1. Preface The goal of this Fortran tutorial is to give a quick introduction to the most common features of the Fortran 77 programming language. It is not a complete reference! Many details have been omitted. The presentation focuses on scientific computations, mainly linear algebra. The outline of this tutorial was inspired by the excellent book "Handbook for Matrix Computations" by T.F. Coleman and C. Van Loan, published by SIAM (unfortunately this book is out of print). This tutorial was designed to be used in the course SCCM-001-F: Introduction to Fortran at Stanford University, 1996. Permission to use this tutorial for educational and other non-commercial purposes is granted provided all author and copyright information is retained. Erik Boman, Stanford, December 1995. 2. What is Fortran? Fortran is a general purpose programming language, mainly intended for mathematical computations in e.g. engineering. Fortran is an acronym for FORmula TRANslation, and was originally capitalized as FORTRAN. However, following the current trend to only capitalize the first letter in acronyms, we will call it Fortran. Fortran was the first ever high-level programming languages. The work on Fortran started in the 1950's at IBM and there have been many versions since. By convention, a Fortran version is denoted by the last two digits of the year the standard was proposed. ...
