<div><br></div><div>This interface explores Matlab's Java integration, so it should work under windows just fine (although I have not tried it myself under Windows --- let me know if it works). </div><div><br></div><div>
<b>Looking for .NET volunteers:</b></div><div><br></div><div> This interface is built on top of Jython (Python under Java). There is something called IronPython which implements the Python under Microsofts .NET framework. I believe that porting JyGrADS to work under IronPython/.NET should be relatively straightforward. This would be an interesting OpenGrADS project, but the OpenGrADS developers are already overextended as it is. So, if someone out there would like to champion this .NET project, please drop us a not at <a href="mailto:opengrads-devel@lists.sf.net">opengrads-devel@lists.sf.net</a>. Some familiarity with .NET and Python (or willingness to learn it) is necessary.</div>
