Detailed Description

template<typename scalar_t>
class strumpack::kernel::DenseKernel< scalar_t >

Arbitrary dense matrix, with underlying geometry.

This is a subclass of Kernel. It overrides the eval routine, unlike other kernel classes (Gauss and Laplace), which only implement the kernel function.
