clear

Clear variables from the model workspace of a model

Syntax

clear(mdlWks)

clear(mdlWks, varName)

clear(mdlWks) removes all variables from the model workspace represented by the Simulink.ModelWorkspace object mdlWks.

clear(mdlWks, varName) removes the variable with the name varName from the model workspace mdlWks.

Open the example model vdp.

openExample('simulink_general/VanDerPolOscillatorExample')

Create a Simulink.ModelWorkspace object that represents the model workspace of vdp.

mdlWks = get_param('vdp','ModelWorkspace');

Create a variable named myVar with value 5.12 in the model workspace.

assignin(mdlWks,'myVar',5.12)

Clear all variables from the model workspace, including myVar.

clear(mdlWks)

Open the example model vdp.

openExample('simulink_general/VanDerPolOscillatorExample')

Create a Simulink.ModelWorkspace object that represents the model workspace of vdp.

mdlWks = get_param('vdp','ModelWorkspace');

Create a variable named var1 with value 5.12 in the model workspace.

assignin(mdlWks,'var1',5.12)

Create another variable named var2 with value 7.5 in the model workspace.

assignin(mdlWks,'var2',7.5)

Clear variable var1 from the model workspace.

clear(mdlWks, 'var1')

Target model workspace, specified as a Simulink.ModelWorkspace object.

Name of variable to remove, specified as a string or a character vector.

Clear variables from a model workspace by using a Simulink.data.DataConnection object function.
```
mw = Simulink.data.connect("vdp.slx");
clearAll(mw);
```
Clear a specified variable from the model workspace by using a Simulink.data.DataConnection object function.
```
mw = Simulink.data.connect("vdp.slx");
clear(mw,"myVar");
```
Clear multiple specified variables from the model workspace by using a Simulink.data.DataConnection object function.
```
mw = Simulink.data.connect("vdp.slx");
clear(mw,["x" "y"]);
```
