I compared the performance of C-style arrays with valarray. My conclusion is that accessing and setting elements makes no difference (sometimes C-syle array's were just 2% faster, but sometimes valarray was 2% faster (5000000 samples)). But the allocation and initialisation of the valrray was like 30% faster, so it might be a good idea to change my C-style array to valarray. It is also nicer in use, one can use functions like sum, etc. How valarray manages memory may also be more efficient, but all i know is that a valarray<double> is bigger than a double* (in means of sizeof()), but that is not really an issue. So valarray!!!
