Member Function Documentation

analyzePattern()

template<class Derived >

Derived & Eigen::PardisoImpl< Derived >::analyzePattern

(

const MatrixType &

matrix

)

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()

factorize()

template<class Derived >

Derived & Eigen::PardisoImpl< Derived >::factorize

(

const MatrixType &

matrix

)

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()

info()

template<class Derived>

ComputationInfo Eigen::PardisoImpl< Derived >::info ( ) const

inline

Reports whether previous computation was successful.

Returns

Success if computation was succesful, NumericalIssue if the matrix appears to be negative.

pardisoParameterArray()

template<class Derived>

ParameterType& Eigen::PardisoImpl< Derived >::pardisoParameterArray ( )

inline

Warning

for advanced usage only.

Returns

a reference to the parameter array controlling PARDISO. See the PARDISO manual to know how to use it.

solve() [1/2]

template<class Derived>

template<typename Rhs >

const internal::solve_retval<PardisoImpl, Rhs> Eigen::PardisoImpl< Derived >::solve ( const MatrixBase< Rhs > &  b ) const

inline

Returns

the solution x of \( A x = b \) using the current decomposition of A.

solve() [2/2]

template<class Derived>

template<typename Rhs >

const internal::sparse_solve_retval<PardisoImpl, Rhs> Eigen::PardisoImpl< Derived >::solve ( const SparseMatrixBase< Rhs > &  b ) const

inline

Returns

the solution x of \( A x = b \) using the current decomposition of A.
