Determination of the weighting coefficients for differential quadrature method based on spline interpolation

Artur Krowiak

Abstrakt

The paper deals with the methodology of the determination of the weighting coefficients for differential quadrature method based on spline interpolation. Appropriate formulas are derived and two practical approaches to determine mentioned coefficients are proposed, one – pure numeric, the other that uses symbolic-numeric programming. Both approaches are analyzed on account of efficiency, conditioning of the problem and easiness of the implementation.
