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.
