Abstract: The present paper introduces a function written in GNU Octave language for
calculating Smith's Mean Measure of Divergence (MMD). The function uses by default
the Freeman and Tukey angular transformation but also provides an optional choice for
Anscombe's transformation. The Freeman and Tukey correction term is used in both cases.
The function calculates the distance and variance matrices of MMD for an arbitrary number
of groups (populations) of samples and trait frequencies. The generated matrices are
returned in the Phylip format for direct use with tree construction tools.
Key words: GNU Octave language; Smith's MMD; distance matrix; non-metric traits
