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)^6 * ( 35 * (rn)^2 + 18rn + 3), where rn is the radius r normalized over the support radius sr: rn = r/sr.
