METIS is a software package for partitioning unstructured graphs, partitioning meshes, and computing fill-reducing orderings of sparse matrices. Important note: this is not the original METIS, it has been specially patched by EDF to be used by Code_Aster.

LASPack (version 1.12.2) LASPack is a package for solving large sparse systems of linear equations like those which arise from discretization of partial differential equations. Main features: - The primary aim of LASPack is the implementation of efficient iterative methods for the solution of systems of linear equations. - Beside the obligatory Jacobi, succesive over-relaxation, Chebyshev, and conjugate gradient solvers, LASPack contains selected state-of-the-art algorithms which are commonly used for large sparse systems: - CG-like methods for non-symmetric systems: CGN, GMRES, BiCG, QMR, CGS, and BiCGStab, - multilevel methods such as multigrid and conjugate gradient method preconditioned by multigrid and BPX preconditioners. A complete description of the package (including the installation procedure) you may find in LASPack Reference Manual:

libranlip is a C++ library created by G. Beliakov, which generates random variates with arbitrary Lipschitz-continuous densities via the acceptance / rejection method. The density should have a dimension of no more than about five. The user needs to supply the density function using a simple syntax, and then call the methods of construction and generation provided in libranlip.

libtsnnls is a fast solver for least-squares problems in the form Ax = b under the constraint that all entries in the solution vector x are non-negative.

ltl2ba implements an algorithm of P. Gastin and D. Oddoux to generate Buechi automata from linear temporal logic (LTL) formulae. This algorithm generates a very weak alternating automaton and then transforms it into a Buechi automaton, using a generalized Buechi automaton as an intermediate step. Each automaton is simplified on-the-fly in order to save memory and time. As usual the LTL formula is simplified before any treatment. ltl2ba is more efficient than Spin 3.4.1, with regard to the size of the resulting automaton, the time of the computation, and the memory used.

basecalc came with Xlib Programming Manual from O'Reilly as an example of X lib programming. mbasecalc is an immitation of basecalc which is available on different platforms.

ndiff is a utility for comparing putatively similar files, ignoring small numeric differences. The utility is written by Nelson H. F. Beebe and covered by the GNU General Public License (GPL), version 2. It may be built with arbitrary precision support (more powerful) or using built-in floating point precision, see Makefile. Assessing the consistency of a numerical program run in multiple environments (operating systems, architectures, or compilers) can be a difficult task for a human, as small differences in numerical output values are expected. File differencing utilites, such as diff(1), will generally produce voluminous output, often longer than the original files. ndiff solves this problem. Taking two text files expected to be identical, or at least numerically similar, it allows to specify absolute and/or relative error tolerances for differences between numerical values in the two files, and then reports only the lines with values exceeding those tolerances. It also tells by how much they differ. A simple example: % ndiff --relative-error 1.0e-3 test019.txt.1 test019.txt.2 ### Maximum relative error in matching lines = 8.64e-51 at line 129 field 4

A perl extension module for scientific data access via the netCDF API

`Oleo' has more than one user interface. The traditional `oleo' environment shows a curses based (character mode) user interface. A bare bones user interface based on the X Window System exists as of version 1.6 which dates back to 1994. In 1998, development started for a `motif' based user interface. It should be more user friendly than the character based UI.
