Syntax

saveToSource(mdlWks)

Description

saveToSource(mdlWks) saves the variables in the model workspace represented by the Simulink.ModelWorkspace object mdlWks to the MAT-file or script file specified by the FileName property of the model workspace.

When you set the DataSource property of the model workspace to 'MAT-File' or 'MATLAB File', the FileName property specifies the name of the file that acts as the external data source of the workspace. As you make changes to the variables in the model workspace, use saveToSource to permanently save the changes in the external data source.

If an object loaded into the model workspace uses a Simulink.CoderInfo object to specify code generation settings, Simulink® removes the Simulink.CoderInfo object and saves the information in the code mapping object for the model.

Examples

collapse all

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 some variables in the model workspace.

assignin(mdlWks,'myVar',5.12)
assignin(mdlWks,'myOtherVar',7.22)

Configure the model workspace to use a MAT-file named myVars.mat as the data source.

mdlWks.DataSource = 'MAT-File';
mdlWks.FileName = 'myVars.mat';

Save the variables to the external data source (the MAT-file).

saveToSource(mdlWks)

The file appears in your current folder.

Input Arguments

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

Alternatives

Save the changes to a model workspace by using a Simulink.data.DataConnection object function.

Update the value of a variable in the model workspace. Then save the change.

mw = Simulink.data.connect("myModel.slx")
mw.x = mw.x + 2;
success = saveChanges(mw)

success = 

logical
    1

Check whether the model workspace contains unsaved changes.

dirty = hasUnsavedChanges(mw)

dirty = 

logical
    0
