[SciPy-user] extracting z, v from a 3D array

Hi,

In a 3D array, each cell [i, j, k] has a value v which is the value at 
the point x=i*dx, y=j*dy, z=k*dz.

How can I extract, "efficiently" (fast and memory resource) the 2D array 
(v, z), ie z vs. v ?

"fast and memory resource" means "in acceptable time": for instance, I 
compute an histogram using scipy.histogram for a 800x850x900 cells float 
array in 3 mn.


TIA.

Cheers,
