CPS615 Foils -- Fortran 90 Language and Simple Examples

Given by Nancy McCracken and Geoffrey C. Fox at CPS615 Basic Simulation Track for Computational Science on Fall Semester 95. Foils prepared 21 Sept 1995

This introduces array notation and describes basic array operators
Array Constructors and Array Sections
The Where Construct
Forall available in some compilers and critical for parallelism
Subroutines and Interfaces
Intrinsic Functions
A simple Gauss-Jordan Matrix Inversion is used as an example

Table of Contents for CPS615 Foils -- Fortran 90 Language and Simple Examples

There are two types of foils -- html and image which are each available in basic and JavaScript enabled "focused" style
(basic:)(focus style:) Denote Foils where Image Critical
(basic:)(focus style:) Denote Foils where HTML is sufficient
