MOMENT estimates the p-th moment 
 
 M = moment(x, p [,opt] [,DIM])
 M = moment(H, p [,opt])
   calculates p-th central moment from data x in dimension DIM
	of from Histogram H

 p	moment of order p
 opt   'ac': absolute 'a' and/or central ('c') moment
	DEFAULT: '' raw moments are estimated
 DIM	dimension
	1: STATS of columns
	2: STATS of rows
