function y = noy(x)
% PURPOSE: This function computes the triweigh kernel
%--------------------------------------------------------------
% USAGE: y = noy(x)
% where:   x =  (1 x n) vector of the points where you want to compute the Kernel 
%--------------------------------------------------------------
% OUTPUTS: y = values of the Kernel (1 x n)
