Followup question -- I've now come across a lot of discussion about windows
boxes and memory problems under IDL (David Fanning, thats a terrific website
you have (http://www.dfanning.com/)-- wish I had found it a few weeks ago!).
Do these problems simply not exist on UNIX boxes (given ample amount of RAM
+ pagefile space)? I reprogrammed a slow but memory conservative version of
this algorithm I'm working on using a bunch of for-next loops -- after all
the discussion I've been seeing about how for-next loops stink, I recoded
the algorithm using mostly matrix calls -- but of course I need more memory
to do these, hence the array has too many elements error. I'm tempted to
switch over to a slower UNIX box if this memory problem won't show up...
thoughts?
