from Fitting NURBS to a given set of data points by Vikash Gupta
Given a set of six points a closed NURBS curve is used to approximately fit all the six data points.

evaluatefunction(P,A)
function [fnvalue] = evaluatefunction(P,A) [C(:,1),C(:,2)]=getbspline(P); %generating closed B-Spline [sqerror,indices]=getdistance(C,A); %computing error or the objective fnvalue=sqerror;
