In this paper we will solve the interpolation problem on two dimension, that is given k points (xi,yi,ci), i=1,2,...,k, we will found continuous function U(x,y) such that U(xi,yi)=ci, i=1,2,...,k and U minimizing integral energy order N. The support points (xi,yi) did not have rectangular grid form. We will use tensor product of two Chebychev systems as a base of interpolation function space.
