I also thought so but if I have to make intensive calculations I have to turn to c++, matlink etc.............then boh.... >The execution speed advantage of C++ is more than >offset by the development time for the program. true on light calculations not true for greater projects >=46or any non-trivial program written in Mathematica code, you >will be making use of Mathematica function that would have to be >re-written in C++ code.And even if this is not the case, things >that take several lines of C++ code tend to take much fewer >lines of code in Mathematica. But if these objects I cannot use them to perhaps make intensive calculations it was better that I immediately wrote them in c++ ..imho >This is an inherent advantage of >using a higher level functions available in Mathematica and not >available in C++. scientific interpreters exist also for the c++ with numerical libraries.... then at the end.... boh cristian
