JyGrADS is a repackaging of the Python Interface to GrADS (PyGrADS) for use under Java, and through Java, for interfacing to any Java-friendly application such as MATLAB. At the core of JyGrADS is Jython, an implementation of the high-level, dynamic, object-oriented language Python written in 100% Pure Java, and seamlessly integrated with the Java platform.
