Scilab - Aplicações Científicas para Linux

Para o pessoal que precisa de uma ferramenta *do tipo* Matlab e não tenham
digamos assim, suporte financeiro para bancar a compra de
um, existe um pacote do INRIA ( Institut National de Recherche en
Informatique et Automatique ) que cumpre com galhardia este papel. ;))
Ele tem até um suporte bastante extensivo para correr códigos para o
Matlab. Acredito que valha a pena conhecer.
Integrado ao pacote vem a "toolkit" "Scicos: a dynamic systems modeler
and simulator". Creio que pode ser uma ferramenta importante para
simulação de sistemas.
Além dos códigos fontes estão disponíveis binários para :
scilab-2.5-0.i386.rpm RPM for the Linux libc6 elf format
scilab-2.5-bin-Linux-i686.tar.gz non RPM for the Linux libc6 elf format
scilab-2.5-bin-alpha-OSF1-V4.0.tar.gz version for Dec Alpha V4.0
scilab-2.5-bin-HP-UX-B.10.20.tar.gz binary version for HP9000
scilab-2.5-bin-Linux-ppc.tar.gz binary version for Linux PPC
scilab-2.5-bin-solaris-5.6.tar.gz binary version for SUNSOLARIS
scilab-2.5-windows.exe binary version for Windows 9X/NT
Segue adiante o anúncio da liberação de uma nova versão do pacote.

Scilab Group proudly announces the release of Scilab-2.5
What is Scilab?
Scilab is a scientific software environment for numerical
computations. It resembles Matlab/Simulink and MatrixX/SystemBuild
of products. Scilab is developed at INRIA and is available via anonymous
ftp in source and binary formats:
ftp.inria.fr in directory INRIA/Scilab
What is new?
Global variables have been introduced
Integer data types have been added.
New graphic mode has been added to allow scrollbar handling (panner
for X Window and scrollbars for Windows).
GIF export format is now available for Scilab graphic windows.
Keyboard events and window closing within graphical windows can now be
Scicos graphical user interface has been made more intuitive and
keyboard shortcuts have been added.
Scilab Binary files created by "save" are now system-independent so
they can be exchanged. In particular (compiled macros) *.bin files and
*.cos (scicos diagrams) can be exchanged.
It is now possible to dynamically link C++ procedures with Scilab.
A new data type "mlist" has been added.
A new function "genlib" allows users to compile the .sci files in a
given directory, generate associated library and load it. This
function is particularly useful under windows if VC++ is not
C formatted input output functions (printf, scanf, ..) have been
interfaced to scilab.
Efficiency has been improved using reference argument passing when
possible instead of value passing.
Hypermatrix opreations have been accelerated.
On X Window systems 3D Athena Widgets are used when available instead of
standard Athena Widgets for a better look.
The "Matlab 4" to Scilab translator has been completed and considerably
What do we expect from Scilab users
Contributions! Here are a few possibilities.
Now that the integer data types are made available in Scilab:
an image processing toolbox.
Read, write and processing of sound signals.
A statistical toolbox.
An identification toolbox.
A signal processing toolbox for Scicos.
Scientific course notes using Scilab (in all languages); note that if
you write a book in which you propose Scilab examples and exercises,
you can distribute Scilab on CD with the book.
GUI interface based on the tcl/tk interface.
A good place to discuss such projects is the scilab newsgroup.
Scilab: is it really free?
Yes it is. Scilab is not distributed under GPL or other standard
free software copyrights (because of historical reasons), but Scilab is
an Open Source Software and is free for academic and industrial use,
without any restrictions. There are of course the usual restrictions
concerning its redistribution; the only specific requirement is that we
ask Scilab users to send us a notice (email is enough). For more details
see Notice.ps or Notice.tex in the Scilab package.
Answers to two frequently asked questions:
Yes, Scilab can be included a commercial package (provided
proper copyright notice is included).
Yes, Scilab can be placed on commercial CD's (such as various
Merry Christmas and happy Scilabing
