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`.
