Add a port of ndiff:

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

Add math/koctave, a KDE GUI for the math/octave package.  It contains
an editor with syntax highlighning and a help browser; you can work
almost the same way as in Matlab (c) , i.e. use the editor and execute
your code from there with (F5) or press run.  One difference is the
command window; it is meant for "quick commands" and not a history as
in Matlab you can add commands to the list in settings.

two dimensional geometry and mesh. We can create and modify the

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 numbers can be any number of digits, with any decimal

        'mp_precision', which can be any reasonable integer, limiting
        only the number of digits to the right of the decimal point.
