Numerical Differentiation and Integration through Aitken-Neville Schemes
International Journal of Analysis and Applications, 2013 Some new formulas are given to approximate higher order derivatives and integrals through Aitken-Neville iterative schemes for arbitrary spaced grids. An algorithm is given in MATLAB for numerical differentiation. Also, numerical examples are provided to

Univariate spline quasi-interpolants and applications to numerical analysis
, 2005 We describe some new univariate spline quasi-interpolants on uniform partitions of bounded intervals. Then we give some applications to numerical analysis: integration, differentiation and approximation of ...

Simple and Accurate Formulas for Flow-Curve Recovery from Couette Rheometer Data
Applied Rheology, 2006 In Couette rheometry, most of the current flow-curve recovery algorithms require the explicit numerical differentiation of the measured angular velocity data. The exceptions and popular choices, because it avoids the need for a numerical differentiation,
