Hi Numarray and Numeric are great modules. I was using them a lot in my scripts. But now the time has come that I would like to write a somewhat bigger application and perhaps even need to write extensions for one of the numerical modules or Scipy. Now, I'm wondering which module to choose: Numarray (my preferred choice so far), Numpy, or "Numeric3"? How far is the latter grown with respect to the other two? How soon will it replace Numpy in SciPy releases? How long will all three co-exist, when will the merger be finished? How long will Numarray and Numpy be supported once Numeric3 "is ready"? Squeezed into one question: What is the state of the art and how can people like me (at the borderline between users and developers) plan ahead? I know that some of these questions are hard if not impossible to answer, but this was really a burning issue to me, since after all the discussions here on the list I am a little clueless. TIA Cheers Christian
