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. ...

RLaB is an interactive, interpreted scientific programming environment which provides fast prototyping and program development. Its syntax is a combination of c (curly brackets for blocks of statement, some statements) and fortran/matlab (c) (indexing of arrays starts from 1, naming of the functions). Project rlabplus provides second update to RLaB2 and third release RLaB3 of the environment for 32- and 64-bit linux systems.

...The convenient visual interface and the detailed manuals are provided. The main benefit of the package is its capability to construct models of any level of complexity in a block-by-block manner. Elementary model blocks can be collected in libraries, and we have already written many such library programs. Many of these programs are already available along with the main package. Currently, the main focus of these is computational quantum mechanics, analysis and simulation of molecular spectra, and general-purpose approximants. The package provides the most reliable modern strategies for linear and non-linear model optimization, regularization, and hypothesis tests. ...
