and numerical analysis, very similar to Matlab.
Yorick's array syntax, interpreted programs are compact,
nearly free of explicit loops, and can run at speeds up to
20% of optimized compiled speed.
It can do interactive graphics via the X Window System,
including x-y plots, quadrilateral meshes and cell arrays.
Includes tools to assist making animated and simple 3d
graphs.
Supports output directly to your screen, in PostScript and
binary CGM format.

like a financial spreadsheet. When invoked it presents you
with a table organized as rows and columns of cells. If
invoked without a file argument, by default the initial
table is empty.
Each cell can be associated with a numeric value, a label
string and/or an expression which evaluates to a numeric
value or label string, often based on other cell values
(formula).

Math::GMP is designed to be a drop-in replacement both for Math::BigInt
and for regular integer arithmetic. Unlike BigInt, though, Math::GMP
uses the GNU gmp library for all of its calculations, as opposed
to straight Perl functions. This results in a speed increase of
anywhere from 5 to 30 times.
A Math::GMP object can be used just as a normal numeric scalar would
be -- the module overloads the normal arithmetic operators to provide
as seamless an interface as possible.
efficiently solves systems of linear equalities and inequalities.
Constraints may be either requirements or preferences. Client code
specifies the constraints to be maintained, and the solver updates the
constrained variables to have values that satisfy the constraints.
A technical report is included in the distribution that describes the
algorithm, interface, and implementation of the Cassowary solver.
Additionally, the distribution contains toy sample applications
written in Smalltalk, C++, Java, and Python, and a more complex
example Java applet, the "Constraint Drawing Application".

also performs standart or Monte Carlo simulations. It allows you
to specify a set of linear or nonlinear equations and solve them
using parameter values you choose or parameter values sampled
from specified statistical distributions. Outputs can be compared.
It consists of two pieces - a model generator and a simulation
engine. The model generator was created to facilitate the model
maintenance and simulation definition, while keeping execution
time fast. Other programs have been created to the same end, the
Matlab family of graphical interactive programs being some of the
more general and easy to use.

wmcalc is a program designed to act as a simple four-function
calculator. It is different from other calculator programs,
however in that it is designed to take up very little desktop
space.
functions like f(x) = x^4 - 2. It allows you to view/compare
multiple function's graphs simultaneously, using different colours.
Geg can zoom in/out selections, and is very easy to use by math
students and teachers, providing nice gtk interface.

by Victor Shoup. It provides objects and methods for
- arbitrary length integers
- finite fields
- polynomials over fields
- extensions of fields.
NTL's lattice reduction code is also one of the best available anywhere, in
terms of both speed and robustness, and one of the few implementations of block
Korkin-Zolotarev reduction with the Schnorr-Horner pruning heuristic. It has
been used to "crack" several cryptosystems.

data access and a library that provides an implementation of the
interface. The netCDF library also defines a machine-independent
format for representing scientific data. Together, the interface,
library, and format support the creation, access, and sharing of
scientific data. The netCDF software was developed at the Unidata
Program Center in Boulder, Colorado.
