[Octave-patch-tracker] [patch #8303] vectorized parcellfun and pararrayfun

[John Hunt]

Follow-up Comment #8, patch #8303 (project octave):

"IdxDimensions", [0, 0, 0, 0, 1, 1, 1, 0], 
"CatDimensions", [4 4 3]
so the indexing is along "n4".
Only e, f and g are indexed (they are column vectors with n4 elements).
All other are passed to and used by the function "as is"
(indicated by 0 in IdxDimensions)

I just realized that indexing is quite simple in this case. 
This shows mainly the benefits of CatDimensions.
I also routinely use more intricate ones (indexing multidimensional arrays,
not simple vectors). More on that later if you wish.
