Member Function Documentation

void analyzePattern

(

const MatrixType &

)

[inline]

Returns:

the solution x of using the current decomposition of A.

See also:

compute() 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()

Reimplemented in SuperILU< _MatrixType >, and SuperLU< _MatrixType >.

Referenced by SuperLU< _MatrixType >::analyzePattern(), and SuperILU< _MatrixType >::analyzePattern().

void compute

(

const MatrixType &

matrix

)

[inline]

Computes the sparse Cholesky decomposition of matrix

ComputationInfo info

(

)

const [inline]

Reports whether previous computation was successful.

Returns:

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

superlu_options_t& options

(

)

[inline]

Returns:

a reference to the Super LU option object to configure the Super LU algorithms.

const internal::solve_retval<SuperLUBase, Rhs> solve

(

const MatrixBase< Rhs > &

b

)

const [inline]

Returns:

the solution x of using the current decomposition of A.

See also:

compute()
