IDL and Matlab Folks,
I have just started working at a laboratory with some expertise in Matlab and
none
in IDL or PV-WAVE. I have been an IDL user for a decade and am trying to decide
whether I should make the effort to get the scientists and programmers to think
about
using IDL. I would especially appreciate any input from people who have used
the
latest versions of both programming environments.
Some of the features we will need:
- ability to run on OpenVMS Alpha, Windows NT, possibly Unix
- easy to develop GUIs
- a robust set of mathematical and image processing tools
- good performance
I would appreciate any constructive input.
Thanks.
--Harvey

matlab works on them and many others. not sure about idl. see

personally, i hate guide (the matlab gui tool) and all other automagic
tools. i like coding things myself. (1) i don't trust them, (2) i
understand things a lot better when i do them myself, analogous to the
difference between memorizing an equation and being able to derive it.

$900 for pcs, 2k for unix.

i've written code in both, and i much prefer matlab. however, that's
speaking mainly from a programming point of view. imho, the idl
language is an abortion. functions have arguments (normal) and keywords
(not normal). the syntax is horrendous.
otoh, in my limited use of envi, which is written in idl, there seem to
be some things that envi does (presumably in idl, but possibly in c, c++
or fortran) much better than matlab, namely dealing with images (speed,
smooth graphics).
overall, i'd **DEFINITELY** pick matlab.

I got two responses from people who had used both environments and were
clear that, although both languages could do what we need, Matlab was
easier to use and had more tools and better support.
Do any users of IDL feel otherwise?
