Detailed Description

template<class Container>
struct dg::InverseKroneckerTriDiagonal2d< Container >

Fast inverse tridiagonal sparse matrix in 2d \( T_y^{-1}\otimes T_x^{-1}\).

When applied to a vector, uses Thomas algorithm to compute \( T^{-1} v\) first row-wise in x and then column-wise in y

Attention

Only for shared memory vectors (works for GPUs but is not fast)
