Simulink.ConfigSet

R2026b

Model configuration set

expand all in page

Description

Use the Simulink.ConfigSet object to access a model configuration set. Get information about your configuration set and manage configuration parameters.

The Simulink.ConfigSet object is a handle object.

Creation

Use the getActiveConfigSet function to get the active configuration set for a model. Use the getConfigSet function to get a model configuration set by name.

Properties

expand all

Description of the configuration set, specified as a character vector. Use the description to provide additional information about a configuration set, such as its purpose.

Name of the configuration set, specified by a character vector. This name represents the configuration set in the Model Explorer.

Object Functions

copyCopy configuration set or reference
get_paramGet parameter names and values
set_paramSet Simulink parameter value
isequalDetermine whether model configuration sets have same parameter values

Examples

collapse all

Open the model vdp and get the active configuration set.

openExample('simulink_general/VanDerPolOscillatorExample');
configSetObj = getActiveConfigSet('vdp');

Specify the configuration set to use for a simulation using a Simulink.ConfigSet object. The sim function applies the configuration set for the simulation without dirtying the model. Changes to the model revert when the simulation completes.

A configuration set specifies only model configuration parameter values. To specify additional values, such as variable and block parameter values, use a Simulink.SimulationInput object instead.

Suppose you want to simulate the model IntegrateSine, described in Run Simulations Using Current Parameter Values, for 20 seconds using the solver ode45.

Block diagram of the model IntegrateSine.

To specify the parameter values to use in the simulation, create and configure a Simulink.ConfigSet object.

  1. Open the model.

  2. Get the configuration set for the model.

  3. Create a copy of the model configuration set.

  4. Specify the stop time and solver on the copy of the model configuration set.

mdl = "IntegrateSine";
open_system(mdl)
mdlconfig = getActiveConfigSet(mdl);
simconfig = copy(mdlconfig);

Simulate the model using the configuration set simconfig.

out = sim(mdl,simconfig);

To see the parameter values used in the simulation, check the simulation metadata returned with the simulation results.

slvr = out.SimulationMetadata.ModelInfo.SolverInfo.Solver
slvr =

    'ode45'
tstop = out.SimulationMetadata.ModelInfo.StopTime
tstop =

    20
