Blitz++ is a high-performance vector mathematics library written in C++. This library is intended for use in scientific applications that might otherwise be implemented with Fortran or MATLAB.

Blitz++ utilizes advanced C++ template metaprogramming techniques, including expression templates,{{cite journal |title=Scientific Computing: C++ Versus Fortran |first=Todd |last=Veldhuizen |year=1997 |journal=Dr. Dobb's |url=http://www.drdobbs.com/cpp/scientific-computing-c-versus-fortran/184410315}} to provide speed-optimized mathematical operations on sequences of data without sacrificing the natural syntax provided by other mathematical programming systems. Indeed, it has been recognized as a pioneer in the area of C++ template metaprogramming.David Abrahams, Aleksey Gurtovoy: C++ Template Metaprogramming: Concepts, Tools, and Techniques from Boost and Beyond, Addison-Wesley, {{ISBN|0-321-22725-5}}
