## Member Function Documentation

 auto Reaktoro::DaeSolver::setOptions ( const DaeOptions & options ) -> void

Set the options for the ODE solver.

DaeOptions
 auto Reaktoro::DaeSolver::setProblem ( const DaeProblem & problem ) -> void

Set the ODE problem.

DaeProblem
 auto Reaktoro::DaeSolver::initialize ( double tstart, const Vector & y ) -> void

Initializes the ODE solver.

This method should be invoked whenever the user intends to make a call to DaeSolver::integrate.

Parameters
 tstart The start time of the integration. y The initial values of the variables
 auto Reaktoro::DaeSolver::integrate ( double & t, Vector & y ) -> void

Integrate the ODE performing a single step.

Parameters
 [in,out] t The current time of the integration as input, the new current time as output [in,out] y The current variables as input, the new current variables as output
 auto Reaktoro::DaeSolver::integrate ( double & t, Vector & y, double tfinal ) -> void

Integrate the ODE performing a single step not going over a given time.

Parameters
 [in,out] t The current time of the integration as input, the new current time as output [in,out] y The current variables as input, the new current variables as output tfinal The final time that the integration must satisfy
 auto Reaktoro::DaeSolver::solve ( double & t, double dt, Vector & y ) -> void

Solve the ODE equations from a given start time to a final one.

Parameters
 [in,out] t The current time of the integration as input, the new current time as output dt The value of the time step [in,out] y The current variables as input, the new current variables as output
