class

`SushiDSP::dk::DenseLu< 1 >`

template <>

One-dimensional LU, which is a single division; the nonlinear diode fast path pays nothing for the general machinery.

Static public attributes

static constexpr double kMinimumPivot = 1e-300

Smallest pivot magnitude accepted as non-singular.

bool factorise(const std::array< std::array< double, 1 >, 1 > &matrix)

Stores the single matrix entry as the pivot.

Parameters

Returns

False when the entry is numerically zero.

bool factorise(const std::array< std::array< double, 1 >, 1 > &matrix, std::size_t order)

Stores the single matrix entry, or succeeds trivially at order zero.

Parameters

Returns

False when the entry is numerically zero at order one.

void solve(const std::array< double, 1 > &right_hand_side, std::array< double, 1 > &solution) const

Divides by the factorised entry.

Parameters

void solve(const std::array< double, 1 > &right_hand_side, std::array< double, 1 > &solution, std::size_t order) const

Divides by the factorised entry, or leaves the solution alone at order zero.

Parameters
