householderSequence()

template<typename VectorsType , typename CoeffsType >

HouseholderSequence<VectorsType,CoeffsType> Eigen::householderSequence	(	const VectorsType &	v,
		const CoeffsType &	h
	)

Convenience function for constructing a Householder sequence.

\

Returns

initParallel()

void Eigen::initParallel ( )

inline

Must be call first when calling Eigen from multiple threads

klu_solve()

int Eigen::klu_solve ( klu_symbolic *  Symbolic, klu_numeric *  Numeric, Index  ldim, Index  nrhs, double  B[], klu_common *  Common, double    )

inline

A sparse LU factorization and solver based on KLU.

This class allows to solve for A.X = B sparse linear problems via a LU factorization using the KLU library. The sparse matrix A must be squared and full rank. The vectors or matrices X and B can be either dense or sparse.

Warning

The input matrix A should be in a compressed and column-major form. Otherwise an expensive copy will be made. You can call the inexpensive makeCompressed() to get a compressed matrix.

Template Parameters

_MatrixType

the type of the sparse matrix A, it must be a SparseMatrix<>

Variable Documentation

Dynamic

const int Eigen::Dynamic = -1

This value means that a positive quantity (e.g., a size) is not known at compile-time, and that instead the value is stored in some runtime variable.

Changing the value of Dynamic breaks the ABI, as Dynamic is often used as a template parameter for Matrix.

DynamicIndex

const int Eigen::DynamicIndex = 0xffffff

This value means that a signed quantity (e.g., a signed index) is not known at compile-time, and that instead its value has to be specified at runtime.

exponents

EIGEN_DEVICE_FUNC const Eigen::ArrayBase<Derived>& Eigen::exponents

Initial value:

{
    typedef typename internal::promote_scalar_arg<typename Derived::Scalar,Scalar,
                                                  EIGEN_SCALAR_BINARY_SUPPORTED(pow,Scalar,typename Derived::Scalar)>::type PromotedScalar

HereditaryBits

const unsigned int Eigen::HereditaryBits

Initial value:

= RowMajorBit
                                  | EvalBeforeNestingBit

HugeCost

const int Eigen::HugeCost = 10000

This value means that the cost to evaluate an expression coefficient is either very expensive or cannot be known at compile time.

This value has to be positive to (1) simplify cost computation, and (2) allow to distinguish between a very expensive and very very expensive expressions. It thus must also be large enough to make sure unrolling won't happen and that sub expressions will be evaluated, but not too large to avoid overflow.

Infinity

const int Eigen::Infinity = -1
