create a blank system 'untitled'
%To add a subsystem 'contoller' >> add_block('simulink/Ports & Subsystems/Subsystem','untitled/controller'); %To add a signal builder >> add_block('simulink/Sources/Signal Builder','untitled/sig'); %To connect the signal builder to the subsystem >> SubsysPortHandles = get_param('untitled/controller','PortHandles'); >> SigPortHandles = get_param('untitled/sig','PortHandles'); >> add_line('untitled',SigPortHandles.Outport(1),SubsysPortHandles.Inport(1))
For more information on ADD_BLOCK and ADD_LINE please refer the MATLAB documentation:
