a map into numbers. The image file can come from a scanner, digital camera or
screenshot. The numbers can be read on the screen, and written or copied to a
spreadsheet.
fastest matrix solver available for FreeBSD. It requires a F90 compiler
so it's built with gfortran, however care was taken to ensure it will
work with g77 while a the default compiler is changed.

The jsMath package provides a method of including mathematics in HTML pages
that works across multiple browsers under Windows, Macintosh OS X, Linux and
other flavors of unix. jsMath uses native fonts, so they resize when you
change the size of the text in your browser, they print at the full resolution
of your printer, and you don't have to wait for dozens of images to be
downloaded in order to see the mathematics in a web page. There are also
advantages for web-page authors, as there is no need to preprocess your
web pages to generate any images, and the mathematics is entered in TeX form,
so it is easy to create and maintain your web pages.
Although it works best with the TeX fonts installed, jsMath will fall back
on a collection of image-based fonts (which can still be scaled or printed
at high resolution) or unicode fonts when the TeX fonts are not available.

decomposed into tasks which are assigned to different processors. Efficient use
of the machine requires that each processor have about the same amount of work
to do and that the quantity of interprocessor communication is kept small.
Finding an optimal decomposition is provably hard, but due to its practical
importance, a great deal of effort has been devoted to developing heuristics
for this problem.
The decomposition problem can be addressed in terms of graph partitioning. Rob
Leland and I have developed a variety of algorithms for graph partitioning and
implemented them into a package we call Chaco. The code is being used at most
of the major parallel computing centers around the world to simplify the
development of parallel applications, and to ensure that high performance is
obtained. Chaco has contributed to a wide variety of computational studies
including investigation of the molecular structure of liquid crystals,
evaluating the design of a chemical vapor deposition reactor and modeling
automobile collisions.

Among other small changes, Elmer calls umfpack routines from f90 using
umf4_f77wrapper.c from umfpacks demo directory. The elmer-umfpack build
compiles this and includes it in the libumfpack.a.

CGAL is a collaborative effort of several sites in Europe and Israel. The goal
is to make the most important of the solutions and methods developed in
computational geometry available to users in industry and academia in a C++
library. The goal is to provide easy access to useful, reliable geometric
algorithms.
The CGAL library contains:
* the Kernel with geometric primitives such as points, vectors, lines,
predicates for testing things such as relative positions of points, and
operations such as intersections and distance calculation.
* the Basic Library which is a collection of standard data structures and
geometric algorithms, such as convex hull in 2D/3D, (Delaunay)
triangulation in 2D/3D, planar map, polyhedron, smallest enclosing
circle, and multidimensional query structures.
* the Support Library which offers interfaces to other packages, e.g., for
visualisation, and I/O, and other support facilities.

I'd like to reintroduce VTK 4.3 to the ports tree to
facilitate building a new port, Caret 5.3. Starting with
VTK 4.4, support for "float" coordinates has been dropped
from many functions. The Caret code will require significant
changes to compile with VTK 4.4. Since the Caret developers
do not yet have a timeline for upgrading to VTK 4.4, I'd
like to reintroduce VTK 4.3 for the interim. Only the vtk
base and vtk-headers are essential. Below are shar files
for these two trees. They are based on the original vtk
4.3 port. The only modifications are:
1. The folder names are changed from vtk and vtk-headers
to vtk43 and vtk43-headers to prevent a collision with the
current vtk in /usr/ports/math.
2. PREFIX is set to ${LOCALBASE}/vtk43 to prevent a collision
with the current vtk installation.
