Detailed Description
Base class of LL' solvers. The input matrices must be selfadjoint (symmetric) It already implements the standard LL' decomposition.Member Function Documentation
| virtual bool tngmath::SparseLLT::Solve | ( | const MatrixBase & | b, | |
| MatrixBase & | x | |||
| ) | [virtual] |
Factorizes this matrix and solves the given vector on return; returns true if succeeded
Reimplemented from tngmath::SparseSolver.
| virtual bool tngmath::SparseLLT::SolveInPlace | ( | MatrixBase & | b | ) | [virtual] |
Factorizes this matrix and solves the given vector in place; returns true if succeeded
Reimplemented from tngmath::SparseSolver.
Reimplemented in tngmath::SparseUpperLLT, tngmath::SparseLowerLLT, tngmath::SparseLLTCholmod, tngmath::SparseUpperLLTCholmod, and tngmath::SparseLowerLLTCholmod.
