Many options and further matrix operations are available. Both Sparse BLAS and the own interfaces are supported (C/C++, Fortran). You can also use librsb transparently in a Matlab-style fashion via the GNU Octave `sparsersb` package and command, or in Python via the `pyrsb.rsb_matrix` class inspired by `scipy.sparse` classes. - This release improves the build process across operating systems (e.g. *BSD, IBM AIX, Mac OS), architectures (armhf,sparc64), compilers and shells. - Numerous compatibility-oriented configure options. - Full changes list on http://librsb.sourceforge.net/NEWS.TXT The source code of librsb is LGPLv3 licensed.
