Fortran 90 Software Repository

Why not contribute some of your own code?

New contributions will be accepted if they are short, concise examples of specific features of the Fortran 90, 95 or 2000 language. Whole packages, libraries or items that compete with our libraries and software tools business will not be accepted.

If you are interested in contributing code, please email webmaster@nag.com.

Important Note:

NAG does not accept any responsibility for the content or performance of this contributed software or the consequences of its use.
