Graphical Programming Language

Hi,
is there some block-based graphical programming language
like e.g. DASYLab or LabVIEW? I'd like to have one that:
- is free, if possible, ow low-cost
- runs under Linux
- is extensible by user-written blocks
I want to use it as a simple tool to try out signal processing
algorithms.

Regards
Martin

Scilab http://www.scilab.org is a open source Matlab clone. It comes 
with a Simulink like tool called Scicos http://www.scicos.org/

Another one that comes to my mind if you are looking toward digital 
communications is Simthetic http://simthetic.sourceforge.net/

It seems like it was a student project, with the goal to implement an 
OFDM transmission system.

Thanks for the answer. It is not free, it is far from free!
There exists a student version, but this applies only to
"active" (*) students, not professionals who want to enlarge
or deepen their knowledge in their free time, something
like a "personal" license.

Thank you
Martin

(*) for want of a better word: those guys that are incribed
at an university in view of getting a degree at some time in
the future. If I think back of my student's days, "active" is
perhaps the wrong word ...

Wow, thanks! I heard about Scilab, I didn't know that a
Simulink clone is included.

Not only that -- IIRC, even the student version was brutally
expensive;  a few months ago I wanted to buy to be able to
get the courses and research work done at home on Linux
(instead of at School with those WinXP pieces of crap), and
the minimally useful configuration for my needs was already
more than 700 US$ -- yes, *student* price!!

It really beats me how those thieves have succeeded in
making that product *the* standard for DSP and many other
scientific/engineering areas.  Oh well, such is the world
where we live  :-)

You might try ptolemy.  I haven't looked at it in about five years 
though, but back then it was fairly impressive.

Here's a link:

Yep, that's way too expensive for a student. A personal
edition for a professional, maybe, although also here,
$700 is steep.

I wouldn't call them "thieves". For the price, you get a
darned good product with good support. That's possibly why
it has become the standard.

Check out R at:

   http://www.r-project.org/

They say it's for statistical programming but that only 
applies to the mass of library packages included with it. 
The language itself has no bias and is an extremely well 
thought out system.

Much thought was also put into presentation support, i.e. 
graphics.
