MATLAB: How can I unlock a library file (not a library block) by command line.

Question

how can I unlock a library file (not a library block) by command line? for example, open a myLib.slx file and need to edit. The first thing need to do is to unlock this model. So Simulink will show: Attempt to modify 'untitledLib', which is or is in a locked library. The action performed requires you to unlock this library.So I need to hit * unlock this library. but i want to do this by command line. it seems set_param(gcb, 'Lock', 'off'); set_param(gcb, 'LinkStatus', 'inactive') are not works.

Answer 1

Have you tried it on the library itself instead of the blocks??? GCB is for blocks, I would recommend the following

 >> set_param(gcs,'Lock','off')
