Fast C routines (Single Percision)
FFTW is a C subroutine library for computing the Discrete Fourier Transform
(DFT) in one or more dimensions, of both real and complex data, and of
arbitrary input size. We believe that FFTW, which is free software, should
become the FFT library of choice for most applications. Our benchmarks,
performed on a variety of platforms, show that FFTW's performance is
typically superior to that of other publicly available FFT software.
Moreover, FFTW's performance is portable: the program will perform well on
most architectures without modification.
The FFTW package was developed at MIT by Matteo Frigo and Steven G.
Johnson. Please send email to fftw@theory.lcs.mit.edu so that we can keep
track of users and send you information about new releases. The latest
version of FFTW, benchmarks, links, and other information can be found at
the FFTW home page

LAPACK95 is a Fortran 95 interface to the Fortran 77 LAPACK library.
It improves upon the original user-interface to the LAPACK package,
taking advantage of the considerable simplifications which
Fortran 95 allows. The design of LAPACK95 exploits assumed-shape arrays,
optional arguments, and generic interfaces. The Fortran 95 interface
has been implemented by writing Fortran 95 ``wrappers'' to call
existing routines from the LAPACK package. This interface can persist
unchanged even if the underlying Fortran 77 LAPACK code is rewritten to
take advantage of the new features of Fortran 95.

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 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

Emc2 is a portable, interactive and graphic software Edition of
two dimensional geometry and mesh. We can create and modify the
geometry (CAD), define the discretization on the lines, define
the subdomains, and define some reference numbers to take into
account the boundary conditions and material properties. The
elements of the mesh are triangles and quadrilaterals. We have
two kind of meshes: grid mesh and Delaunay Voronoo (automatic
mesh). We make the edition of the mesh by moving, removing,
adding vertices, by regularization, or by transformations
(symmetry, rotation,..), etc.

Mpexpr adds two new commands to Tcl, 'mpexpr' and 'mpformat'.
Mpexpr works much like Tcl's native 'expr', but does all
calculations using an arbitrary precision math package.
Mpexpr numbers can be any number of digits, with any decimal
precision. Final precision is controlled by a Tcl variable
'mp_precision', which can be any reasonable integer, limiting
only the number of digits to the right of the decimal point.
