Detailed Description

Solves Mx = b for x, where M is a SparseMatrix.

Member Enumeration Documentation

DataType

enum TBTK::LUSolver::DataType

strong

Enum class for specifying the data type of the matrix. Used since complex matrices that are purely real are converted to double type for optimization.

Constructor & Destructor Documentation

LUSolver()

TBTK::LUSolver::LUSolver

(

)

Constructs a Solver::LUSolver.

~LUSolver()

TBTK::LUSolver::~LUSolver

(

)

Destructor.

Member Function Documentation

getMatrixDataType()

LUSolver::DataType TBTK::LUSolver::getMatrixDataType ( ) const

inline

Get matrix data type. Is None before a matrix has been set, Double if a real matrix has been set, and ComplexDouble if a complex matrix has been set. Note that a SparseMatrix<std::complex<double>> is stored as Double internally if the matrix is real.

Returns

The data type that is used to store the data.

setMatrix() [1/2]

void TBTK::LUSolver::setMatrix

(

const SparseMatrix< double > &

sparseMatrix

)

Set matrix.

Parameters

sparseMatrix

Matrix \(M\) to use in the equation \(Mx = b\).

setMatrix() [2/2]

void TBTK::LUSolver::setMatrix

(

const SparseMatrix< std::complex< double >> &

sparseMatrix

)

Set matrix.

Parameters

sparseMatrix

Matrix \(H\) to use in the equation \(Mx = b\).

solve() [1/2]

void TBTK::LUSolver::solve

(

Matrix< double > &

b

)

Solve for \(x\) in the equation \(Mx = b\).

Parameters

b	The vector \(b\). Contains the answer \(x\) when finished.

solve() [2/2]

void TBTK::LUSolver::solve

(

Matrix< std::complex< double >> &

b

)

Solve for \(x\) in the equation \(Mx = b\).

Parameters

b	The vector \(b\). Contains the answer \(x\) when finished.
