Advanced modern Fortran

Overview

This 5-day course provides an introduction to the rest of the capabilities of modern Fortran, including generic programming, object oriented programming, parameterised derived types, exception handling using IEEE facilities, C interoperability and parallel programming.

The course is suitable for people who have attended the Introduction to modern Fortran course, or have a basic grounding in Fortran or a good grounding in another programming language.

The course is also suitable for people wanting to convert from another language and already have a basic grounding in Fortran.

All our courses are a mixture of lectures and practical sessions.
