Hi, guys:
I want to write a function which can be apply to specified dimension of multiple array, like "mean function which has DIMENSION= parameters.
So, any suggestions! Very thanks!

I guess this depends on what you want the function to do?

You can have a look at Markwardt's CMAPPLY (Apply generic function to array)
http://www.physics.wisc.edu/~craigm/idl/down/cmapply.pro

I also have done something similar but with a different approach. But I never had time (or just too lazy) to clean up the code to a state that it can be published on its own ...

Hi, Carsten:
Your method using "tranpose" is what I am doing now.
And if I want to extrat elements, just use like
array[1,*,*,*,*,*,*,*], which can apply to arbitrary
dimension array. Very thanks!
