Neglegting the NaNs would make more sense to me (treating them as NA), but
that would be something like:
b = [2 5 NaN 7];
b(isnan(b)) = []
b =
2 5 7
cumsum(b)
ans =
2 7 14
which is different. And maybe that is a reason - nancumsum would be ambigous
(treat the NaNs as 0 or treat them as nonexisting?).
nansum is not ambigous.
