Detailed Description

template<class Container>
struct dg::KroneckerTriDiagonal2d< Container >

Fast tridiagonal sparse matrix in 2d \( T_y\otimes T_x\).

Consists of Two TriDiagonal matrices \( T_x\) and \( T_y\)

Note

It is fast to apply using dg::blas2::parallel_for (which only works on shared memory vectors though)

Template Parameters

Container

One of the shared memory containers
