[opendx-users] accessing elements of array

[Betsy Foote]

I have 3D data that I have extracted just the z positions:

    data -> Slice -> Slice -> Extract

So now I have an array containing just the z positions (the z positions
are the same given any x and y).

How do I access the individual elements of the array?

What I want to create is another array which contains the deltas between
the z positions. Something like:

        for (i=0; i<n-1; i++)
           deltas[i] = array[i+1] - array[i]


I can't figure out how to do this in DX.

Can someone help?

Thanks,

Betsy
