A:
After reshaping, padColor is a 1-by-1-by-3 array. Since the size of the first two dimensions is 1, padColor(:,:,1), which means padColor("all","all",1) is equivalent to padColor(1,1,1). In other words, padColor(:,:,1) is the element you find in the first row, first column, first 'z-slice' of padArray.

How can a 1-1-1 array be reshaped into a 1-1-3 array?Or more generally,into a m-n-k array?

Your original array is not 1-by-1-by-1; it's 1-by-3.
