Specify model solver options
The SolverOptions property is an object that
holds the model solver options in the configset object.
Changing the property SolverType changes the options
specified in the SolverOptions object.
Properties of SolverOptions are summarized
in Property Summary.
| AbsoluteTolerance | Absolute error tolerance applied to state value during simulation |
| AbsoluteToleranceScaling | Control scaling of absolute error tolerance during simulation |
| AbsoluteToleranceStepSize | Initial guess for time step size for scaling of absolute error tolerance |
| ErrorTolerance | Specify explicit or implicit tau error tolerance |
| LogDecimation | Specify frequency to log stochastic simulation output |
| MaxIterations | Specify nonlinear solver maximum iterations in implicit tau |
| MaxStep | Specify upper bound on ODE solver step size |
| OutputTimes | Specify times to log deterministic simulation output |
| RandomState | Set random number generator |
| RelativeTolerance | Allowable error tolerance relative to state value during a simulation |
| SensitivityAnalysis | Enable or disable sensitivity analysis |
| Type | Display SimBiology object type |
| Applies to | Object: configset |
| Data type | Object |
| Data values | Solver options depending on SolverType.
Default is SolverOptions for default SolverType (ode15s). |
| Access | Read-only |
This example shows the changes in SolverOptions for
various SolverType settings.
Retrieve the configset object from
the modelObj.
modelObj = sbiomodel('cell');
configsetObj = getconfigset(modelObj);Configure the SolverType to ode45.
set(configsetObj, 'SolverType', 'ode45'); get(configsetObj, 'SolverOptions') Solver Settings: (ode) AbsoluteTolerance: 1.000000e-006 RelativeTolerance: 1.000000e-003
Configure the SolverType to ssa.
set(configsetObj, 'SolverType', 'ssa'); get(configsetObj, 'SolverOptions') Solver Settings: (ssa) LogDecimation: 1 RandomState: []
Configure the SolverType to impltau.
set(configsetObj, 'SolverType', 'impltau'); get(configsetObj, 'SolverOptions') Solver Settings: (impltau) ErrorTolerance: 3.000000e-002 LogDecimation: 1 AbsoluteTolerance: 1.000000e-002 RelativeTolerance: 1.000000e-002 MaxIterations: 15 RandomState: []
Configure the SolverType to expltau.
set(configsetObj, 'SolverType', 'expltau'); get(configsetObj, 'SolverOptions') Solver Settings: (expltau) ErrorTolerance: 3.000000e-002 LogDecimation: 1 RandomState: []
