Detailed Description

template<class Tscal>
class shammath::details::KernelDefTGauss5< Tscal >

Truncated Gaussian kernel with compact support R=5h.

W(q) = exp(-q^2) for q < 5, 0 otherwise

Extended support version of TGauss3. Provides even smoother behavior at the cost of more neighbor interactions.
