A simplicial direct Cholesky (LDLT) factorization and solver based on Cholmod.
This class allows to solve for A.X = B sparse linear problems via a simplicial LDL^T Cholesky factorization using the Cholmod library. This simplicial variant is equivalent to Eigen's built-in SimplicialLDLT class. Thefore, it has little practical interest. The sparse matrix A must be selfajoint and positive definite. The vectors or matrices X and B can be either dense or sparse.
_MatrixType | the type of the sparse matrix A, it must be a SparseMatrix<> |
_UpLo | the triangular part that will be used for the computations. It can be Lower or Upper. Default is Lower. |
This class supports all kind of SparseMatrix<>: row or column major; upper, lower, or both; compressed or non compressed.
