Numerical
software is specialized code used to analyze, model, or compute
numeric,
symbolic, or geometric information. Many numerical suites are computer
algebra
systems that use symbolic algebra. They are designed to solve classical
equations and tasks in closetocommon notation. This is a short list
of helpful
options...
Scilab
is an open source software with a GPL compatible licence. The Scilab
Consortium
is involved in the Open Source world in a number of ways. Libraries are
free
with accepted and recognized licenses by the Free, Libre, Open Source
Software
(FLOSS) community.
Scilab
Examples in this site
ScicosLab
is the new name of ScilabGtk. This change of name has been taken in
order to
avoid confusion with Scilab, which is no longer developed at INRIA.
ScicosLab
is used in particular for disributing new software developments from
research
activities of the Metalau team at INRIA and ENPC, such as Scicos and
the Maxplus
toolbox.
Octave  gnu.org/software/octave
GNU
Octave is a highlevel interpreted language, intended for numerical
computations. It provides capabilities for the numerical solution of
linear and
nonlinear problems, and for performing other numerical experiments. It
also
provides graphics capabilities for data visualization and
manipulation. The
Octave language is quite similar to Matlab so that most programs are
easily
portable.


JMathLib
is a clone of Matlab, but written entirely in java. A
library of functions designed to be used in evaluating complex
expressions and
display the results graphically. It’ll be used either interactively
through a
terminal like window or to interpret script files. It is intended to be
a java version
of programs such as Matlab, Scilab, Octave, and FreeMat.
Maxima
is a software for the manipulation of symbolic and numerical
expressions,
including differentiation, integration, Laplace transforms,
differential
equations, systems of linear equations, polynomials, lists, vectors,
matrices,
and tensors. Maxima produces high precision numeric results by using
exact
fractions, arbitrary precision integers, and variable precision
floating point
numbers. It can plot functions and data in 2D and 3D. Maxima is a
descendant of
Macsyma, the computer algebra system developed at the MIT.
The
Euler Mathematical Toolbox is a powerful, mature software for numerical
and
symbolic computations. Euler is similar to Matlab, but has an own
style, and a
slightly different syntax. Symbolic mathematics is supported in Euler
using the
open algebra system Maxima.
FreeMat
is an environment for rapid engineering and scientific prototyping and
data
processing. Similar to commercial systems such as Matlab and IDL, but
it’s open
source. It’s available under the GPL license.
GTK+ is
a highly usable toolkit for creating graphical user interfaces. It has
an easy
to use API and it’s written in C, but has bindings to many other
popular
programming languages such as C++, Python and C# among others. GTK+ has
been
involved in many projects and some big platforms.
A
programming language for numerical analysis. Algae was developed
because of the
need of a fast and versatile tool, capable of handling large systems.
Algae has
been applied to interesting problems in aerospace and related fields
for more
than a decade.
NumPy
and SciPy are two of many opensource packages for scientific computing
that
use the Python programming language.
