4D concat % Only three levels of variable concatenation are allowed.

Hi all

problem:

IDL> a=make_array(3,3,3,2)
IDL> help,a
<Expression>    FLOAT     = Array[3, 3, 3, 2]
IDL> help,[[[[[a]]],[[[a]]]]]

% Only three levels of variable concatenation are allowed.

solution:

IDL> help,concatenate_arrays(a,a,3)
% Compiled module: CONCATENATE_ARRAYS.
<Expression>    FLOAT     = Array[3, 3, 3, 4]



you can get this function from

http://www.fz-juelich.de/icg/icg-1/idl_icglib/idl_source/idl_work/fr_lib/concatenate_arrays.prohelp,concatenate_arrays(a,a,3)

and some others
