Standard deviation of a datetime array.
S = std (A) returns the standard deviation of the
absolute instants of A as a duration. The weight w
selects the normalisation (0, the default, divides by ;
1 divides by ), and a dim or 'all' argument
selects the dimension(s). Missing-value handling matches mean.
[S, M] = std (…) also returns the mean M as
a datetime.
