harmmean - Harmonic mean
Syntax
m = harmmean(X)
harmmean(X,dim)
Description
m = harmmean(X) calculates
the harmonic mean of a sample. For 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.
harmmean(X,dim) takes the harmonic mean
along dimension dim of X.
The harmonic mean is
Examples
The arithmetic mean is greater than or equal to the harmonic
mean.
x = exprnd(1,10,6);
harmonic = harmmean(x)
harmonic =
