Hi Sasa, questions, improving the performance of the Mathematica code are often posted. Many people think, that usual approaches will help, if you write c, c++ or pascal code sometimes combined with the Compile[]. Read a book or join a online course programming in Mathematica by WRI and find out how to use l = Table[Sin[x], {x, 0, 10 Pi, 10 Pi/10^6}] // N; Plus @@ l // Timing or Select[], /@ and & (pure functions) etc.. The Mathematica help system is also useful if you look for @@ and then open one item under see also.
