This (sparsersb) is a plugin to interface the "librsb" high performance sparse
matrix library to GNU Octave.
Author: Michele MARTONE

Build / use instructions (using pkg):

To use the configure auto-detected librsb from within Octave:
 > pkg -local -verbose install sparsersb-1.0.9.tar.gz
 > pkg load sparsersb
 > help sparsersb

Alternatively:
 tar czf sparsersb-1.0.9.tar.gz
 cd sparsersb-1.0.9/src
 ./configure
 make
 make check

It is possible to provide the configure script with a librsb sources 
archive you have downloaded separately and make it build on the fly for you
and use it; e.g.: 
 ./configure --with-librsb-tarball=$HOME/librsb-1.2.0.10.tar.gz
or setting:
 export LIBRSB_TARBALL=$HOME/librsb-1.2.0.10.tar.gz
before entering in Octave and building with pkg:
 > pkg -local -verbose install sparsersb-1.0.9.tar.gz

On many systems, you will have to build librsb with the PIC (-fPIC on GCC)
option or you will get link-time problems.

More configure options:
./configure --help

Usage instructions without using pkg:
# go to the directory where sparsersb.oct is located and run Octave:
octave
# you can use the sparsersb function, starting with e.g.:
 > help sparsersb
