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 WebExcel GEOMEAN Function The GEOMEAN function returns the geometric mean of an array or range of positive numbers. The geometric mean can be used for a set of numbers whose values are meant to be multiplied together or are exponential in nature, e.g., a set of growth figures. Excel TRIMMEAN Function
