Scalar type

Required Methods

fn assemble_pairwise_st( &self, sources: &[<Self::T as RlstScalar>::Real], targets: &[<Self::T as RlstScalar>::Real], result: &mut [Self::T], )

Evaluate the kernel values for all source and target pairs

For each source, the kernel is evaluated for exactly one target. This is equivalent to taking the diagonal of the matrix assembled by assemble_st

fn assemble_st( &self, sources: &[<Self::T as RlstScalar>::Real], targets: &[<Self::T as RlstScalar>::Real], result: &mut [Self::T], )

Evaluate the kernel values for all sources and all targets

For every source, the kernel is evaluated for every target.
