Detailed Description

template<typename MatrixType>
class Eigen::PardisoLU< MatrixType >

A sparse direct LU factorization and solver based on the PARDISO library.

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

Template Parameters:
_MatrixTypethe type of the sparse matrix A, it must be a SparseMatrix<>

Member Function Documentation

Derived & analyzePattern ( const MatrixType &  matrix) [inherited]

Performs a symbolic decomposition on the sparcity of matrix.

This function is particularly useful when solving for several problems having the same structure.

See also:
factorize()
Derived & factorize ( const MatrixType &  matrix) [inherited]

Performs a numeric decomposition of matrix

The given matrix must has the same sparcity than the matrix on which the symbolic decomposition has been performed.

analyzePattern()
ComputationInfo info ( ) const [inline, inherited]

Reports whether previous computation was successful.

Returns:
Success if computation was succesful, NumericalIssue if the matrix appears to be negative.
ParameterType& pardisoParameterArray ( ) [inline, inherited]
Warning:
for advanced usage only.
Returns:
a reference to the parameter array controlling PARDISO. See the PARDISO manual to know how to use it.
const internal::solve_retval<PardisoImpl, Rhs> solve ( const MatrixBase< Rhs > &  b) const [inline, inherited]
Returns:
the solution x of $ A x = b $ using the current decomposition of A.

const internal::sparse_solve_retval<PardisoImpl, Rhs> solve ( const SparseMatrixBase< Rhs > &  b) const [inline, inherited]
Returns:
the solution x of $ A x = b $ using the current decomposition of A.
