harmean

harmean — harmonic mean

Calling sequence

hm=harmean(x)  
hm=harmean(x,'r')(or,  equivalently,   hm=harmean(x,1))  
hm=harmean(x,'c')(or,   equivalently,  hm=harmean(x,2))

Parameters

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 .
