      Blitz++ is a C++ class library for scientific computing which provides
      performance on par with Fortran 77/90. It uses template techniques to
      achieve high performance. Blitz++ provides dense arrays and vectors,
      random number generators, and small vectors (useful for representing
      multicomponent or vector fields).
