Perhaps test with a 2D array first, so you can see how the
indices change in 2D, then 3D may be obvious.

I think the nidex for them are
C: 18,23,20,7,4,19
IDL: 23,12,16,2,17,4

To make the mapping easier, can you make the C matrix 1...24 (or
0...23). Then you might be able to figure out what's going on.
