PURPOSE

CENTER removes the mean

SYNOPSIS

function [i,S] = center(i,DIM,W)

DESCRIPTION

 CENTER removes the mean 

 [z,mu] = center(x,DIM,W)
   removes mean x along dimension DIM

 x    input data 
 DIM    dimension
    1: column
    2: row
    default or []: first DIMENSION, with more than 1 element
 W    weights to computed weighted mean (default: [], all weights = 1)
    numel(W) must be equal to size(x,DIM)

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