harmean

Arguments

x

real or complex vector or matrix

Description

This function computes the harmonic mean of a vector or matrix x. For a vector or matrix x, hm=harmean(x) returns in scalar hm the harmonic mean of all the entries of x.

hm=harmean(x,'r') (or, equivalently, hm=harmean(x,1) ) returns in each entry of the row vector hm the harmonic mean of each column of x.

hm=harmean(x,'c') (or, equivalently, hm=harmean(x,2) ) returns in each entry of the column vector hm the harmonic mean of each row of x.

Examples

harmean(1:10) // Returns 10/sum(1 ./(1:10)) ~ %pi
