类似matlab的c++库，可以再自己的程序中调用！(this is a C++ library for symbolic mathematical calculations. It is designed to allow the creation of integrated systems that embed symbolic manipulations together with more established areas of computer science (like computation-intense numeric applications, graphical interfaces, etc.) under one roof.)
