python2-numexpr 2.6.5 Fast numerical expression evaluator for NumPy

Numexpr is a fast numerical expression evaluator for NumPy. With it, expressions that operate on arrays are accelerated and use less memory than doing the same calculation in Python. In addition, its multi-threaded capabilities can make use of all your cores, which may accelerate computations, most specially if they are not memory-bounded (e.g. those using transcendental functions).
