Fortran
was developed for general scientific computing and is a very popular
language for this purpose. In 1996 it was estimated that Fortran was
employed for more than 90% of scientific computation (see Scientific
Computing World, April 1996). Here is a Fortran
90 Tutorial Course,
from Durham University, that gives you an introduction to
programming in Fortran 90. The elements of programming are introduced
in the context of Fortran 90 and coding examples and exercises are used
to demonstrate their use. Upon finishing this Fortran tutorial course,
you will have enough understanding of programming and Fortran 90 to
code straightforward programs. The course is designed for those with
little or no previous programming experience, but you will need to be
able to work in linux or Unix and use a linux or Unix text editor. (61

This Fortran course
consists of five parts:
- Part 1: Getting
started: programming basics
- Part 2: Input and
output, and using intrinsic functions
- Part 3:
Arrays: vectors and matrices
- Part 4: Program
control: do loops and if statements
- Part 5:
Subprograms: functions and subroutines
