Detailed Description

Wendland radial basis function with compact support.

To be used as template parameter for RadialBasisFctMapping. Takes the support radius (> 0.0) on construction.

Evaluates to: (1 - rn)^10 * (1287*rn^4 + 1350*rn^3 + 630*rn^2 + 150*rn + 15), where rn is the radius r normalized over the support radius sr: rn = r/sr.
