The paper, proposes two new algorithms for the construction of a two-variable Newton-interpolation polynomial, for the special case where we have a rectangular basis with equidistant points. The complexity of the proposed algorithms is better than the ones given in [1] since it is based only on additions. One of the two algorithms is based on matrix multiplications and thus it is easily implemented in programming languages which supports such kind of operations.
