Abstract:

Based on the Lanczos methods revived by Groetsch, a method of differentiation by integration is presented to approximate derivatives of approximately specified functions. The method is applicable for any point in a finite closed interval. Convergence estimates in $C[a,b]$ and $L^{p}[a,b]$ are given. Numerical examples show that the method is simple and applicable.
