Blitz++ utilizes advanced C++ template metaprogramming techniques, including expression templates,^[1] 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.^[2]
