harmeann The harmeann function returns the harmonic mean value of a general lua table that may contain a multi-dimensional array or a mixture of numbers, strings, named keys, and sub-tables. Only numeric values found in the table are used in the calculation. The harmeansdevn function returns both the harmonic mean and standard deviation.
