Abstract
A numerical differentiation problem for a given function with noisy data is discussed in this paper. A Legendre-Gauss-Lobatto interpolation method with a truncated strategy has been introduced to deal with ill-posed ness. The theoretical analysis and numerical results show that the method is effective.
