The harmonic mean of a set of numbers is the reciprocal of the mean of the reciprocals of the numbers.
The function harmonicmean calculates the harmonic mean
of x. The algorithm robustly handles special cases
where some of the values in x are very small or are
exactly equal to zero.
The function harmonicsum calculates the reciprocal of the
sum of the reciprocals of the x values.
