Resumen de Explicit Gaussian quadrature rules for C1 cubic splines with symmetrically stretched knot sequences
Rachid Ait Haddou, Michael Bartoň, Victor M. Calo
We provide explicit expressions for quadrature rules on the space of C1 cubic splines with non-uniform, symmetrically stretched knot sequences. The quadrature nodes and weights are derived via an explicit recursion that avoids an intervention of any numerical solver and the rule is optimal, that is, it requires minimal number of nodes. Numerical experiments validating the theoretical results and the error estimates of the quadrature rules are also presented.
