The NewtonSolverSparse provides access to the sparse linear solver for the Newton method.
Public Functions
-
NewtonSolverSparse(realtype *t, AmiVector *x, Model *model)
Constructor, initializes all members with the provided objects, initializes temporary storage objects and the klu solver.
- Parameters
t – pointer to time variable
x – pointer to state variables
model – pointer to the model object
-
NewtonSolverSparse(const NewtonSolverSparse&) = delete
-
NewtonSolverSparse &operator=(const NewtonSolverSparse &other) = delete
-
~NewtonSolverSparse() override
-
virtual void solveLinearSystem(AmiVector &rhs) override
Solves the linear system for the Newton step.
- Parameters
rhs – containing the RHS of the linear system, will be overwritten by solution to the linear system
-
virtual void prepareLinearSystem(int ntry, int nnewt) override
Writes the Jacobian for the Newton iteration and passes it to the linear solver.
- Parameters
ntry – integer newton_try integer start number of Newton solver (1 or 2)
nnewt – integer number of current Newton step
-
virtual void prepareLinearSystemB(int ntry, int nnewt) override
Writes the Jacobian (JB) for the Newton iteration and passes it to the linear solver
- Parameters
ntry – integer newton_try integer start number of Newton solver (1 or 2)
nnewt – integer number of current Newton step
