blitz: New package, version 0.10 (close #5062)

Fast multi-dimensional array library for C++

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).
