Open the airframe project and create a project object.

sldemo_slproject_airframe;
proj = simulinkproject;

Modify a project model file by adding an arbitrary block.

open_system('AnalogControl')
add_block('built-in/SubSystem', 'AnalogControl/test')
save_system('AnalogControl')

Get all the modified files in the project.

modifiedfiles = listModifiedFiles(proj)

modifiedfiles = 

  1x2 ProjectFile array with properties:

    Path
    Labels
    Revision
    SourceControlStatus

Observe two modified files. Compare with the Modified Files view in Project, where you can see a modified model file, and the corresponding .SimulinkProject definition file.

Get the second modified file.

modifiedfiles(2)

ans = 

  ProjectFile with properties:

Path: 'C:\Work\temp\slexamples\airframe2\models\AnalogControl.slx'
                 Labels: [1x1 slproject.Label]
               Revision: '2'
    SourceControlStatus: Modified

Observe the file SourceControlStatus property is Modified. Similarly, listModifiedFiles returns any files that are added, conflicted, deleted, etc., that show up in the Modified Files view in Project.

Get all the project files with a particular source control status. For example, get the files that are Unmodified.

proj.Files(ismember([proj.Files.SourceControlStatus], matlab.sourcecontrol.Status.Unmodified))

ans = 

  1x29 ProjectFile array with properties:
