|

*
|
||||
*
|
||||
* This module is currently for internal use only
|
||||
*
|
||||
* It defines various built-in and external ordering methods for sparse matrices.
|
||||
* They are typically used to reduce the number of elements during
|
||||
* the sparse matrix decomposition (LLT, LU, QR).
|
||||
* Precisely, in a preprocessing step, a permutation matrix P is computed using
|
||||
* those ordering methods and applied to the columns of the matrix.
|
||||
* Using for instance the sparse Cholesky decomposition, it is expected that
|
||||
* the nonzeros elements in LLT(A*P) will be much smaller than that in LLT(A).
|
||||
*
|
||||
*
|
||||
* Usage :
|
||||
* \code
|
||||
* #include <Eigen/OrderingMethods>
|
||||
* \endcode
|
||||
*
|
||||
* A simple usage is as a template parameter in the sparse decomposition classes :
|
||||
*
|
||||
* \code
|
||||
* SparseLU<MatrixType, COLAMDOrdering<int> > solver;
|
||||
* \endcode
|
||||
*
|
||||
* \code
|
||||
* SparseQR<MatrixType, COLAMDOrdering<int> > solver;
|
||||
* \endcode
|
||||
*
|
||||
* It is possible as well to call directly a particular ordering method for your own purpose,
|
||||
* \code
|
||||
* AMDOrdering<int> ordering;
|
||||
* PermutationMatrix<Dynamic, Dynamic, int> perm;
|
||||
* SparseMatrix<double> A;
|
||||
* //Fill the matrix ...
|
||||
*
|
||||
* ordering(A, perm); // Call AMD
|
||||
* \endcode
|
||||
*
|
||||
* \note Some of these methods (like AMD or METIS), need the sparsity pattern
|
||||
* of the input matrix to be symmetric. When the matrix is structurally unsymmetric,
|
||||
* Eigen computes internally the pattern of \f$A^T*A\f$ before calling the method.
|
||||
* If your matrix is already symmetric (at leat in structure), you can avoid that
|
||||
* by calling the method with a SelfAdjointView type.
|
||||
*
|
||||
* \code
|
||||
* // Call the ordering on the pattern of the lower triangular matrix A
|
||||
* ordering(A.selfadjointView<Lower>(), perm);
|
||||
* \endcode
