Upgrading to Fortran 90 (eBook, PDF)

• Format: PDF

Produktbeschreibung

A comprehensive tutorial that relies mainly on a large number of short, but complete programming examples to illustrate the differences between the new language and traditional Fortran. The author gives thorough explanations of terminology and concepts which were not in general use before the release of the new standard. Readers are assumed to have a working knowledge of one of the earlier versions of Fortran, but otherwise no prior knowledge of Fortran 90 is assumed.
