Hello: I need to write some numerical integration and do Fast Fourier transforms in c++. I am running MS OS on Intel Duo core processors. Earlier post suggested downloading libraries such as MLK. Since I am running on Intel, I have found Intel's MLK library. I will need other libraries along the way. However, before that I need to choose a C++ compiler to download. What are you suggestions? E.g., Intel C++ Compiler vs. MS Visual Studio 2005 vs. MS Visual Studio 2008 etc. Because our problem may not be solved easily in MATLAB. We're moving into C++. Thank you!
