Detailed Description

Concrete class that provides concrete implementations of the singular Jacobian solve methods of the LOCA::Bifurcation::TPBord::AbstractGroup.

The singular Jacobian solve methods are implemented by calling the corresponding compute methods of the LOCA::SingularJacobianSolve::Manager class. It is through this class, and the passed parameter list in the constructor, that the particular algorithm for performing the singular solves is chosen. See the LOCA::SingularJacobianSolve::Manager class description for a description of the relevant parameters and the corresponding singular solve algorithms. In the future, the functionality provided by the manager class will be directly incorporated into this class.

applyJacobianInverse for nearly singular systems

This method is to compute the solution to $Jx=b$ for nearly singular $J$. approxNullVec contains an approximation to the null vector $n$ such that $Jn\approx0$, and jacApproxNullVec contains $Jn$. The idea is these quantities are supposed to help in obtaining an accurate solution to $Jx=b$.

The method is implemented by calling the LOCA::SingularJacobianSolve::Manager::compute() method of the LOCA::SingularJacobianSolve::Manager class.

Implements LOCA::Bifurcation::TPBord::AbstractGroup.

Version of applySingularJacobianInverse() for multiple RHS.

The method is implemented by calling the LOCA::SingularJacobianSolve::Manager::computeMulti() method of the LOCA::SingularJacobianSolve::Manager class.

Implements LOCA::Bifurcation::TPBord::AbstractGroup.
