Blitz++ is a C++ template class library that provides array objects for scientific computing. It is not a linear algebra or fft library; see http://oonumerics.org/oon or http://www.math.unipd.it/~michela/OP.htm for libraries that will do those things.

Blitz has gone through some changes in location:

1. The original Blitz website was located at http://oonumerics.org/blitz.

2. Blitz then moved to SourceForge, at http://www.sourceforge.net/projects/blitz.

3. The latest maintained version of Blitz is now on GitHub, at https://github.com/blitzpp/blitz

Licensing information is detailed in the LEGAL file. Summary: you can do anything except sell this library in source form. Blitz is licensed under either the Lesser GPL version 3 license (see COPYING and COPYING.LESSER), the BSD license (see COPYRIGHT), and the less restrictive Perl "artistic license" version 2.0 (see LICENSE).

Compiling programs

All Blitz++ header files are referred to with a prefix of "blitz/". For example, to use the Array<T,N> class, one needs to include <blitz/array.h> instead of just <array.h>. To make this work, the main Blitz++ directory must be in your include path. For example, if Blitz++ was installed in /software/Blitz++, you will need to compile with -I/software/Blitz++ and -L/software/Blitz++/lib -lblitz

To summarize, a typical command line is:

g++ foo.cpp -o foo -I/software/Blitz++ -L/software/Blitz++/lib -lblitz

To avoid the -I and -L options, you can set up symbolic links -- see INSTALL for details.
