Extrapolation order
Extrapolation order for ode14x
fixed-step solver
Model Configuration Pane: Solver
Description
The Extrapolation order parameter specifies the order of extrapolation
the ode14x
fixed-step solver uses to compute state values.
Dependencies
To enable this parameter when the solver Type is
Fixed-step
, from the Solver list,
select ode14x (extrapolation)
.
To enable this parameter when the solver Type is
Variable-step
:
For the Solver parameter, select
odeN (Nonadaptive)
.For the Integration method parameter, select
ode14x (extrapolation)
.

Higher-order extrapolation is more accurate but also more computationally intensive. The number you select corresponds to the order of extrapolation used. For example, selecting 3
specifies third-order extrapolation.
