use of temporary in IDL [message #81954]

Hi,

I had a question regarding the use of temporary in IDL.
I wanted to re-order a 3D array.
Suppose the array is vol = IntArr( 512, 512, 287 )

I sorted the Z dimension and got the indices. The command I then used was
vol = temporary( vol[ *, *, sorted_z] )

Despite this, the memory used is still the same if I don’t use temporary (almost 5 times the size of the array)

Is this the correct way to use temporary? If I am using it correctly, is it just the IDL way of reading columns and rows?

Thanks,
Rohit
