%X The reconstructions based on 6 kinds of basis functions were compared by computer simulation. The result indicates that the reconstruction based on differentiable basis function is better than that based on non-differentiable basis function and the reconstructions based on different differentiable basis function is approximately the same. The computation of projection matrix is mostly considered for the choice of basis functions.
