Hi.
More I use IDL, more I found strange features. The one I want to talk
about is the way you create multidimensional arrays. Look the following
IDL commands sequence:
IDL> print, [[1, 2], [3, 4]]
1 2
3 4
IDL> a = [1, 2]
IDL> b = [3, 4]
IDL> print, [a, b]
1 2 3 4
Why the same notation has two meanings? Why for the first print the
[something, something_else] notation creates an array of arrays, and for
the second one the same notation concatenates the arrays? I can't find
the logic behind this.
In fact I stopped on this because I want to create an array of images
using something like that: [image1, image2, image3]. What is the way to
do this without creating a new temporary variable array? Or is there a
way to create easily a list of anything.
I want to build a procedure that takes a list of images and displays
them, something like that:
myDisplayProcedure, myImagesList, parameter1, parameter2
where myImagesList is something like that:
{image1, image2, image3}
or anything else that can be create on the command line.
I hope I am clear enough.
Any comments? Any suggestions?
Nicolas.
