I am working with photographic images which use RGB color.
The array d is a single image and the array D is now 2
images but I want D to contain any number of images. And I
want split out the R,G, and B part which I can do for d, but
I am having difficulty with the analogous r, g, and b for D.
0 1 2&|: will do the job.
I recommend reading the dictionary definition of |: through a few times.
In particular, note that 0 1&|: on a rank three array is the same as
2 0 1&|: , and 0 1 2&|: turns into 3 0 1 2&|: on a rank four array.

Perfect.
Something was blocking me.

Something I never wrapped my head around with |: is what exactly the DoJ means
when it says axes are "run together" when the LHA is boxed.

An alternative phrase would be "taking the diagonal".
The "run together" mechanism relates to the distinction between inner
and outer product. If you think of each array having an associated
list of indices along each dimension, normally transpose uses an outer
product combination of these. But wh
That does clear it up (especially the justification of this feature in terms of
inner vs outer products). Thank you.
