[Y_int Phi_int]=rbfn_integral(Xc,X1,X2,W,k_i,basisfunction)

function [Y_int Phi_int]=rbfn_integral(Xc,X1,X2,W,k_i,basisfunction)
%calculates a line integral between X1 [x y] and X2 for a radial basis
%function with center Xc and prescaler k_i
%basis function may be 'gaussian' or 'polyharmonicspline'
%see rbf_integral for more
