CPS615 Foils -- Fortran 90 Language and Simple Examples

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
