Look at ...
help diff
The 2nd input is the order of the difference. Meaning diff(x,2) is equivalent
to diff(diff(x)), and still operates along the 1st dimension.
help cumsum
The 2nd input is the dimension of the ND array to perform the cumsum over.
When you used diff (x, 2) did you want diff (diff (x)) or did you want to
perform the diff along the 2nd dimension of x?
