I need to create a Simulink model using MATLAB commands or scripts. What functions and/or utilities are available to enable me to do this? 

Best Answer

You can create a Simulink model and add blocks/ lines to it using 'add_block' and 'add_line' commands. For example to add a Constant block which provides an input to the To Workspace block to a blank model, you can use the following MATLAB code:
 mdl='myModel';  % this is a blank model at first
  load_system(mdl);  
  add_block('built-in/Constant',[mdl '/Constant'])
  add_block('built-in/To Workspace',[mdl '/Output'],'Saveformat','Array',...
     'SampleTime','-1','VariableName','sim_out','MaxDataPoints','1');
  add_line(mdl,'Constant/1','Output/1','autorouting','on');
For more information on 'add_block'  please refer the MATLAB documentation:

and more information regarding 'add_line' can be found here:

An overarching documentation page regarding Simulink blocks, including modifying the parameters programmatically with 'get_param' and 'set_param' can be found here:
