Thanks to everyone who responded to my question which program to choose,
MATLAB, IDL of PV~WAVE; if you want to do mainly signal processing (in
neurophysiology).
I have had reactions form: Mark Cook, Ralph Finch, Jan Habraken,
Harmonic Software, James Mitchell, Rc Olsen, Darren Orbach, Chris
Ruckman, Philip Turet, and Peter Webb.
I will briefly summarize all the reactions I received (without quoting
the authors, sorry). This summary may not be complete, because I suspect
I lost some messages un UseNet. :(
Please, if you have anything to comment on this, please do.
o Every user was very satisfied about the product he was using. Either
MATLAB, IDL or PV~WAVE.
o Users working with both MATLAB and IDL/WAVE preferred MATLAB for signal
processing.
o MATLAB's Signal Processing Toolbox is very powerful, and there is
nothing like it in IDL/WAVE. Although you could write something
similar with the basic functios IDL/WAVE provide.
o IDL and PV~WAVE are basically the same, just the widgets (user
interface?) are different. One user said WAVE was much more powerful; two
claimed IDL was way better.
o Because of the widgets IDL/WAVE looks more user-friendly.
o IDL/WAVE is more powerful for large programming projects.
o MATLAB does not support 3D matrices, but version 5 will.
o IDL/WAVE is more flexible with different data structures.
o MATLAB has better user support on UseNet.
o There is also O-Matrix with numerous signal processing routines. It is
faster then MATLAB and IDL and is also cheaper.
(NOTE: the information above is taken directly from comments I received.
Most of the information however, were just statements, no
reasoning why.)
Personally I conclude:
o There is no clear winner, any program will do what I want.
o If MATLAB will not support 3D matrices and flexible data structures
in future, this will be a major problem for me.
o I like MATLAB for its user support on UseNet. (25-50 messages a day,
vs IDL with only 5 a day and most questions remaining unanswered!)
IDL/WAVE's policy is to remain silent on UseNet, I really do not understand
why.
o I do not like the yearly licence fee charged by MATLAB, and the expensive
toolboxes which I have to buy seperately.
I have ordered demos from all companies, and will have a closer look at them.
Thanks to all who replied, apologies for not replying you personally. :-)
