Accuracy and Stability of Computing High-order Derivatives of Analytic Functions by Cauchy Integrals
15 years 1 months ago
Abstract High-order derivatives of analytic functions are expressible as Cauchy integrals over circular contours, which can very effectively be approximated, e.g., by trapezoidal s...
