Is there any library including matrix operation?

Is there any library including matrix operation such as matrix multiply ans reverse matrix?

That library is not the C++ standard library. However, I'm also fairly sure such a mathematics library exists. Check Wikipedia, maybe you'll find something.

I'm betting Boost has one (somewhere). Go check out boost.org

i used to see one in a book on numeric algorithm using C++, go find some books related and
you might find one.
