A measure of central tendency is a single value that describes the way … WebFor vectors, harmmean (X) is the harmonic mean of the elements in X. For matrices, harmmean (X) is a row vector containing the harmonic means of each column. For N -dimensional arrays, harmmean operates along the first nonsingleton dimension of X. example m = harmmean (X,'all') returns the harmonic mean of all elements of X. example
