1numexpr - Fast numerical array expression evaluator for Python and NumPy. 2 3The numexpr package evaluates multiple-operator array expressions many times 4faster than NumPy can. It accepts the expression as a string, analyzes it, 5rewrites it more efficiently, and compiles it to faster Python code on the fly. 6It's the next best thing to writing the expression in C and compiling it with a 7specialized just-in-time (JIT) compiler, i.e. it does not require a compiler at 8runtime. 9 10Also, numexpr has support for the Intel VML (Vector Math Library) -- integrated 11in Intel MKL (Math Kernel Library) --, allowing nice speed-ups when computing 12transcendental functions (like trigonometrical, exponentials...) on top of 13Intel-compatible platforms. This support also allows to use multiple cores in 14your computations. 15
