Hi,
Does anyone have the scoop on the newest comment on the ITTVIS web site
about IMSL coming to IDL? Entire library or selected functions? Which
OS? What's the Interface (call external, DLM, etc.)? Free for IDL
customers under maintenance or another $1000 addon? Anything else you
can think of?
Cheers,
Haje

Matt,
well, I'd like to have a bunch of those functions ready to use in IDL,
although I admit I would probably only use a fraction of them. I am not
saying that there are not other solutions (thanks for you link btw).
However, integrating these libraries into IDL via DLM is a lot work and
the time i would need creating my own IMSL DLM for 180 functions would
cost way more than $1000. If you have ever done DLM programming you
know what I am talking about.

Can you explain how you like what you see? What's different? What are
the
real improvements? The more I look at it, the less interesting it
seems. Of
course, when I've had to do any hard core statistical stuff, I've gone
to R
(http://www.r-project.org/index.html) It's free, very well supported,
and
runs most platforms.
So Haje, seriously let me know what's new, better, and how.
Matt

I doubt that IMSL will be included for free in the next IDL version. In
defense of ITTVIS, the excessive licensing cost is not just their
fault. Having bought IMSL previously bundled with a Fortran comiler, my
guess is that they fork out half of the license price to VNI. Left is
$500 for ITTVIS for a 560kB DLM (plus IDL wrappers). Hey, that's less
than $1 per kilobyte of code. :-)
Anyway, I am testing the IMSL lib and my first impression is that I
like what I see. The question is in the end whether I can justify the
spending.

David,
I did some testing with a 2 week demo key and I repeat that did like
what I saw. The problem I have with IMSL that it is kind of like music:
you want it for your ipod you buy it on itunes, you want it on the zune
you pay for it again at microsoft, then you decide you want the CD for
your shelf and you have to pay again, and so on. I already paid
multiple hundred bucks once for IMSL with my Lahey FORTRAN compiler and
I cannot justify to pay for it again. I can implement single functions
via DLMs. However, doing the whole library this way would not be cost
efficient. So really, the blame is on VNI here.
