tdls::detail::ArrowheadStreamedBlock< T, S, B, col, diag > Struct Template Reference

Block k of a streamed solve of ArrowheadLUppSolverStatic (ArrowheadLUppSolverStatic::StreamedBlock): the working arrays of the solver themselves, which the caller fills through the accessors when the solver asks for the block; the factorization and the solve then run in place. Only a save is copied (D_k, and [A_kb | y_k] when the column-major check reads the forward stage), to store a refused block as given. Entries in logical order whatever the layout and the storage. The arrays come uninitialized, or holding another block: the caller writes every entry, zeros included, by assignment. More...

Detailed Description

template<typename T, int S, int B, bool col, bool diag>
struct tdls::detail::ArrowheadStreamedBlock< T, S, B, col, diag >

Block k of a streamed solve of ArrowheadLUppSolverStatic (ArrowheadLUppSolverStatic::StreamedBlock): the working arrays of the solver themselves, which the caller fills through the accessors when the solver asks for the block; the factorization and the solve then run in place. Only a save is copied (D_k, and [A_kb | y_k] when the column-major check reads the forward stage), to store a refused block as given. Entries in logical order whatever the layout and the storage. The arrays come uninitialized, or holding another block: the caller writes every entry, zeros included, by assignment.

Template Parameters

T	scalar type
S	unknowns of a block
B	border unknowns
col	column-major layout
diag	diagonal coupling
