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

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.
(Note to submitter: it is not necessary to remove all the directories
in pkg-plist that are installed by any standard X-related port).

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.
Suggested add-on: the port math/bamg.

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.

round numbers, both positive and negative, in various ways. This may seem like
an odd thing to write a whole module for, but rounding can sometimes be
a little tricky, so I thought some people might find this useful.
