MATHEMATICS Packages
Mathematics Software Packages on Athena
matlab, in the matlab locker. RECOMMENDED
Matlab is a powerful mathematic (and especially matrix)
manipulation program, which works numerically with up to double
precision floating point accuracy. Matlab has a number of
packages directly applicable to engineers, such as plot bode
curves, optimize filters, find filter coefficients, and DSP. A
graphic interface (simulink) can be used to put together and
simulate complicated dynamical systems. SIPB puts out a useful
"Inessential Matlab" document. See also the documentation on
the Mathworks web site:
http://www.mathworks.com/access/helpdesk/help/helpdesk.shtml
xess, in the xess locker. RECOMMENDED
xess is a scientific spreadsheet, which contains a number of
mathematical, statistical, and logical functions, and can draw
(moderately simple) graphs.
maple, in the maple locker. RECOMMENDED
Maple is a symbolic math program (with a somewhat cranky
interface). Some further information on Maple is available at
http://web.mit.edu/maple/www/maple.html
mathematica, in the math locker
Mathematica is a programming environment for performing both
symbolic and numerical calculations as well as displaying and
formatting the output. It can process algebra, calculus,
graphics, sounds, and more, and includes a large set of add-on
packages to customize if for specific tasks such as discrete math,
statistics, linear algebra, and number theory. In addition to
the built in help, there's extensive documentation on the Wolfram
web site:

xcalc (no locker need be attached)
xcalc is a simple scientific calculator.
bc (no locker need be attached)
bc is a simple calculator with a text interface.
sas, in the sas locker.
SAS is an integrated application for data access, management,
analysis, and presentation. Available only on Suns.
These packages vary widely in their capabilities; which is best for
you depends on what you are trying to do. The packages annotated with
RECOMMENDED are the ones that you are most likely to get help on.
----------------------------------------------------------------------
The mathlibrary locker has been set up to make it easier for "one stop
shopping" for mathematical routines for use on Athena. The Mathlibrary
presently includes:
lapack, a library of Fortran subroutines for linear algebra
recipes, the software from the book "Numerical Recipes, the Art of
Scientific Computing"
c++, a collection of c++ code from the netlib server
NA-digest, an archive of the NA-NET news digest
Full details on the locker are in mathlibrary/README. Much of this
stuff is from circa 1997, and seems to have fallen into disrepair;
if you are in need of a particular solution, do ask.
