Close any or all Simulink system windows unconditionally


bdclose closes the current system window unconditionally and without confirmation. Any changes made to the system since it was last saved are lost. To find out the current system, use gcs. If a model was only loaded, bdclose clears the model from memory.


bdclose(sys) closes the specified system window, discarding all changes.

bdclose('all') closes all open system windows, discarding all changes.
