Hi everyone

the first release of the sparsersb package [1] is out, by Michele Martone.

The sparsersb package provides an Octave interface to librsb [2] which
implements the RSB sparse matrix format.  librsb is a library for sparse
matrix computations featuring the Recursive Sparse Blocks (RSB) matrix format.
This format allows cache efficient and multi-threaded (that is, shared memory
parallel) operations on large sparse matrices.  The most common operations
necessary to iterative solvers are available, e.g.: matrix-vector
multiplication, triangular solution, rows/columns scaling, diagonal
extraction / setting, blocks extraction, norm computation, formats
conversion.  The RSB format is especially well suited for symmetric and
transposed multiplication variants. On these variants, librsb has been found
to be faster than Intel MKL's implementation for CSR.  Most numerical kernels
code is auto generated, and the supported numerical types can be chosen by
the user at build time.

Enjoy Octave responsibly,
Carnë
