geomean

PURPOSE ^

GEOMEAN calculates the geomentric mean of data elements.

SYNOPSIS ^

function [y] = geomean(x,DIM,W)

DESCRIPTION ^

 GEOMEAN calculates the geomentric mean of data elements. 
 
     y = geomean(x [,DIM [,W]])   is the same as 
     y = mean(x,'G' [,DIM]) 

 DIM    dimension
    1 STD of columns
    2 STD of rows
    default or []: first DIMENSION, with more than 1 element
 W    weights to compute weighted mean (default: [])
    if W=[], all weights are 1. 
    number of elements in W must match size(x,DIM) 

 features:
 - can deal with NaN's (missing values)
 - weighting of data 
 - dimension argument also in Octave
 - compatible to Matlab and Octave
