And for speed you may be better off with PyPy than with NumPy http://speed.pypy.org/timeline/ but, as is always the case when measuring the speed of things, 'it all depends on what you are doing'. Do you need to link to existing Fortran or C libraries? If the answer is no, and you really only are doing crunching, and your crunching is done in loops which run for a significant amount of time -- then PyPy is generally faster than Fortran. If you are spending most of your time in matplotlib graphing your results, you will be unhappy with PyPy performance. pypy-...@python.org is a better place to discuss performance of PyPy, though while http://mail.scipy.org/mailman/listinfo/numpy-discussion is a better place to discuss numpy. scipy.org has been down all day, alas. But the Americans should be awake now and dealing with it. Laura -- https://mail.python.org/mailman/listinfo/python-list
