All,
I am looking through the IDL documentation and seeing more and more of
the routines that I want to use as part of IMSL, in this instance it
is random numbers from "weird" distributions. This makes we want to
get analyst, I am wondering if the experts on this list are using it?
And if not, why? Too much money? Don't need the features? Already
wrote everything you need? Using something else?
I do notice that most of the things I want (in my looking today) are a
part of the GSL, it is not too hard to write wrappers to GSL code to
make it callable from IDL but that is certainly a heck of a lot more
work than calling IMSL_xxxx.pro.
Thoughts? Comments?
Cheers,
Brian

I am not an expert, but...
originally we were using PV~Wave Advantage here, which is Wave with the
IMSL extra goodies. In our particular usage, which was actually pretty
straightforward image processing, we weren't taking much advantage of
the extras so when we got a good offer from RSI to change to IDL which
gave us a lower annual maintenance bill we moved over and haven't missed
the extras enough to want them back, but that's for straightforward
image processing and relatively lightweight data crunching.

The usual dichotomy here: at some level Time == Money. If you have the
money, it's probably worth spending because you can never get time back
again. If you don't have the money you don't have the choice, of
course. Reinventing the wheel is for either those with no choice or who
have time on their hands, the latter group being something of an empty
set, I suspect!
