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))
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
