Properties
 NameDescription
Public propertyAbsoluteTolerance Bound on the estimated error at each integration step. At the ith integration step the error, e[i] for the estimated solution y[i] satisfies e[i] <= max(RelativeTolerance*Math.Abs(y[i]), AbsoluteTolerance[i])
Public propertyInitialStepSize Suggested initial step size. The solver will try this first. By default the solver determines an initial step size automatically.
Public propertyMassMatrix Gets and sets the Mass matrix M for problems of the form M*y' = F(t,y) where M is a matrix of constant values.
Public propertyMassMatrixFunction Gets and sets the time-state dependent Mass matrix M(t,y) for problems of the form M(t,y)*y' = F(t,y)
Public propertyMaxStepSize Upper bound on step size. Defaults to one-tenth of the times span interval.
Public propertyNormControl Control error relative to norm of solution. If true the solver controls the error, e, in the solution, y, at each integration step by norm(e) <= max(RelativeTolerance*norm(y), AbsoluteTolerance) Default value is false.
Public propertyOutputFunction Delegate for the output function.
Public propertyRefine Increases the number of output points by the specified factor producing smoother output. If Refine is n which is greater than 1, the solver subdivides each time step into n smaller intervals and returns solutions at each time point. The extra values produced for Refine are computed by means of continuous extension formulas The default for RungeKutta45OdeSolver solver is 4.
Public propertyRelativeTolerance Bound on the estimated error at each integration step. At the ith integration step the error, e[i] for the estimated solution y[i] satisfies e[i] <= max(RelativeTolerance*Math.Abs(y[i]), AbsoluteTolerance[i])
